Timber Stack Measurement
It is important to estimate timber volumes accurately either in the forest or when leaving. A number of methods can be used:
 Crop inventory carried out by a qualified professional in the forest prior to felling
 It can be calculated by modern thinning machines as harvesting takes place
 The timber can be measured in the stacks at roadside (see method described below)
 Weighing of the timber as it passes though the mill gate

Timber Stack Measurement
Advantages
It is useful to estimate timber that is stacked at roadside:
 It can be done quickly by the forest owner
 It is useful to know how much timber is leaving the forest
 It is useful to calculate the volume of different individual stacks, which is important if different timber products are being sold separately from the one harvesting operation
Disadvantages
All logs in a stack must be of uniform length and the stack should be built neatly and tidy for easy measurement and accuracy. Large stacking space is required to ensure that all harvested material can be stacked at roadside before any removal is carried out by timber trucks.
Length * Width * Height = Volume (unit = m3)

Some definitions
 Stack width
The width is the specified length of the timber product in the stack. A number of sample lengths
(billets) should be checked to verify the stack width.
 Stack length
Stack length is the average length of the front and back face of the stack. The stack should be measured from the centre point of the outermost billets at one end of the stack to the centre of the outermost billets at the other end.
 Stack height
Stack height is the perpendicular height from the bottom of the stack to the centre of the highest billet at the top of the stack. Average stack height is the average value of a series of height measurements taken along the length of the…...

Performance Measurement

...Introduction When a procedure, a model, an approach, a case study, or other research is undertaken, generally some measure of the system's performance is presented and perhaps analyzed. A large number of different types of performance measures have been used to characterize systems, particularly production, distribution, and inventory systems. Such a large number of available performance measures makes performance measure selection difficult. Generally, performance measurement research focuses on analyzing performance measurement systems that are already in use, categorizing performance measures and then studying the measures within a category, and building rules of thumb or frameworks by which performance measurement systems can be developed for various types of systems. Beamon (1996) presents a number of characteristics that are found in effective performance measurement systems, and can therefore be used in evaluation of these measurement systems. These characteristics include: inclusiveness (measurement of all pertinent aspects), universality (allow for comparison under various operating conditions), measurability (data required are measurable), and consistency (measures consistent with organization goals). Besides analyzing the measures based on their effectiveness, benchmarking is another important method that is used in performance measure evaluation. Benchmarking can be useful in that it can serve as a means of identifying improvement opportunities. Camp (1989)......

Measurement

...Vershire also has some issues on the performance measurement report and evaluation system. Besides the inefficient way to measure manufacturing efficiency, performances of plant managers are measured based on the metric that they cannot directly control, i.e. sales. Therefore the related compensation packages and promotions mislead and lack sufficient incentives to motivate plant managers. As illustrated before, it is inappropriate to treat a plant as a profit center, rather than an expense center. Due to the manufacturing nature, plants have fully control on costs and should be motivated to lower the cost to make contributions to the revenue. Monthly performance evaluation report and supporting report for a plant showing both sales and costs in Exhibit 2 and 3 are submitted by each plant and reviewed by corporate management. Items that failed to meet the budgeted targets require explanations from plant managers, no matter it is cost-related or sales-related. Moreover, sales report on plant basis is confusing by itself since products are sold on district basis. The sales department had sole responsibility for the price and delivery schedules, which are not identical in each order because of contingencies such as traffic, weather, and sick staff. Plant managers have no way to explain the detailed decision making process of sales department to provide a sufficient explanation to sales failures without asking sales department. Furthermore, second-hand information tends to be......

Measurement of Poverty

...Measurement of poverty By Name: Course code+ Name: Professor: Institution: City and State: Date: Measurement of Poverty Over the past few decades, there have been dramatic socio-economic and environmental changes around the globe. This has affected phenomena such as growth of the population, rapid urban development, and increased levels of poverty (D’Ambrosio, Deutsch and Silber, 2011). It has also influenced the changes in climatic conditions, increased natural calamities which impact the socio-economic development in different parts of the world. As a result, more people have been exposed to the negative effects of the occurrence of different hazards (D’Ambrosio, Deutsch and Silber, 2011). This leaves the affected populations suffering in poverty, thus increasing their numbers. Increased levels of poverty led to the formation of policies by the United Nations to combat the rising cases of poverty with the aim of reducing the number of people living in poverty by halve before the year 2015. Formulation of the millennium development goals which features the quantitative objectives and indicators set to measure the progress towards the war on poverty eradication took course. To establish the level of poverty in the society, therefore, measurement should be performed severally using a number of available tools (Davidson and Duclos, 2000). This will aid in determination of the extent of its effects throughout the world. This paper aims at discovering the......

The Stack

...The stack In life problems solved by confrontations is mandatory, no matter how hard you try to avoid them, sooner or later they will catch up, and stacking them instead of confronting them, will only make the problems bigger. Don’t wait for others to do your dishes take responsibility. That is among other things what Rose Tremain writes about in the short story ”The stack”, which was written and published in 2000. The story is told by an 3. Person omniscient narrator bound to John McCreedy. The main theme in the story is family problems that we can see, because the story is about a family that doesn’t function. The communication is bad, and the tone is hard between the members, they don’t like talking to each other and you get the feeling that the members in the family are alienated towards each other. The Story takes place in a small family in London it is in modern time, and about a modern family living in the suburban area. It can be seen through the language represented in the text: “Fuck off, Dad. Everyone remembers their fuckin’ age”. As shown in this quote. The main character is John McCreedy also known as McCreedy, he is father of 2 children and married to Hilda. Original McCreedy is from Ireland, which he misses enormously. He has a drinking problem and spends a little too much time in the pub: “But don’t go and spoil it by going out first and getting sloshed.” Through this quote it gets clear to us, that it is a regular thing for him to drink. We can......

Performance Measurement

...Performance Measurement Robert Campbell MGT/437 March 14, 2011 Sunil Mehta Performance Measurement According to NY Government (n.d.) website, “Strategic, performance measurement-based management systems allow an organization to align its business activities to its strategy, and to monitor performance toward strategic goals over time” (para. 1). Each measurement should be objective, easy to understand, controllable by minimizing outside influences, timely, accurate, cost-effective, useful, motivating, and trackable (NY Government, n.d.). The use of performance measurement is important because the stock market’s volatility has shown that financial measurement is not the only measurement. By using measurement techniques companies can compare themselves to established norms. In this discussion there will be a look at three different types of performance measurement systems, what they do and how they are used. These systems identified are the balanced scorecard, performance dashboards, and the economic value added. The balanced scorecard is a strategic planning and management measurement style widely used throughout the business world to bring its business activities in line with the vision and strategy of the organization (Balanced Scorecard Institute, 1998-2010). According to the Balanced Scorecard Institute (1998-2010) the implementation increases focus on strategy and results, increases organizational performance by measuring what is important, and aligns......

Lab 3 Stacks and Queues

... Q1: What is the initial value of variable Top? The initial value of Top is blank. It is initialized under the array. It is waiting for a number to be set to set a value. Q2: What is the difference between Pop and Peek operations? Pop operations takes of the value at the top of the array. Each time that it is pressed it removes the first value at the top of the array. Peek only returns the value of the item to the top of the stack. So, if the button push is pressed, then that value is inserted to the top of the array. Q3: What are the initial values of Front and Rear? The initial value of the variable Front is the slot in the array spot for 0. The index 0 is where front is placed. The Rear variable is waiting for a value to be inserted to take a spot. This variable will always be the value that was last inserted to the array. Q4: What is the difference between Rem and Peek operations? The operations remove deletes the value at the top of the array. In other words on the rear variable. The peek operation returns the value that the variable rear is pointing to. Q5: What technique in array it used to allow 50 inserted into the queue? Once the array was filled all the way to the top, the pointer came back to the bottom of the array where we had deleted two values. It came down to index 0 and stored the value 50. Q6: What is the difference between priority queue and the regular queue at insertion operations? There is a difference between priority and regular queue. Regular......

Performance Measurement

...Introduction The topic of contrast and comparison contained within this paper consists of the evaluation of three individual performance measurements that exist in management. The individual performance measurements are broken down in order to better understand the inner workings of such measurements goals. Therefore the end result will be measured by how important performance management actually is. In the world of business there are many cliché’s about how performance measurements are implemented and what they actually do such as “if your company doesn’t measure results then you can’t tell success from failure.” http://www.balancedscorecard.org/Home/tabid/36/Default.aspx The key focus on strategic objectives should always articulate precisely what the organization wants to accomplish which is the key to finding accurate, true, strategic measurements. The strategic performance measures will allow the organization to monitor the implementation and effectiveness of the operational efficiency. The best performance measures will provide a way to monitor and see if that strategy is actually working. Focusing on the importance of the employee’s contribution to the success of the organization is another important measure that can be added along with providing a common language for the communication of everyone. Performance measurement is so vital in the structure of an organization because it is an ongoing and constant reporting and monitoring of accomplishments. ......

Oop Stack

...process is a stack which is following the process of Last In First Out (LIFO). Problem 2: Box inside Truck This problem is also a stack related case which is Last in First Out process. Stuff carry and place box 1 then box 2 then… inside the truck. But when they carry out, they will carry the 12th box which is the last box that was put in first. These 2 problem can be simplified into 1 single problems which are box and car are called object the same. Object Oriented Encapsulation (Abstraction) Abstraction is the process of simplifying a difficult problem. We will use abstraction to simplify above problems. Both cars and boxes are object. A B C Stack is like a one way box. First object that goes in, will come out the last. You put object in it, you will pull it back sequentially. To understand the working of Stacks consider for example the data elements:  Data Elements: A , B , C  In the above problem, data elements were entered in the following order A,B,C. In Stack Terminology the elements were pushed in the following order A, B, C.  StackPush Order = A, B, C  Also, we have StackTop = C  Now, if we consider removing the elements also known as popping the element from the stack  StackPop Order = C, B, A  Notice that the StackPop is exactly the reverse of the order in which the data elements were popped.  Thus the most important operations on the Stack Data Structure are: * Push()                  : Inserting an element onto the Stack *......

Measurement

...MEASUREMENT: Measurement is the heart of scientific discipline. It is the process of assigning numbers to objects or observations, the level of measurement being a function of the rules under which the numbers are assigned. According to Zikmund, “Measurement is the process of describing some property of a phenomenon of interest, usually by assigning numbers in a reliable and valid way”. In our daily life we are said to measure when we use some yardsticks to determine weight, height or some other features of a physical object. We also measure when we judge how well we like a song, intelligence, achievement, attitude, perception regarding quality. We, thus, measure physical object as well as abstract concepts. Measurement is a relatively complex & demanding task, especially so when it concerns qualitative or abstract phenomena. So, technically speaking, measurement is a process of mapping aspects of a domain onto other aspects of a range according to some rule of correspondence. It is a collection of quantitative data. TYPES OF MEASUREMENT: 1) Nominal measurement: All qualitative measurements are nominal, regardless of whether the categories differ from one another only in names. Nominal measurements represent the most elementary level of measurement in which values are assigned to an object for identification or classification purposes only. In nominal level of measurement, the categories differ from one another only in names. In other words, one category of a......

Stack Ranking: Brilliant Management or Inherent Absurdity

...Stack Ranking: Brilliant Management or Inherent Absurdity Ray Johnson MGMT E-4000 Organizational Behavior 1 August 2012 Abstract Employee stack ranking is a performance measurement system that requires every manager to rank its employees from excellent to poor. Stack ranking was popularized by Jack Welch at General Electric in the 1980’s. Since that time it has become a popular management technique. The use of stack ranking has many demonstrated successes, but many managers and business analysts are beginning to questions its value to an organization. In this paper I will examine from a critical perspective both the good and bad aspects of stack ranking in an attempt to determine its long term viability as an organization behavior. Stack Ranking: Brilliant Management or Inherent Absurdity Introduction Stack ranking, sometimes referred to as forced distribution, is a popular performance measurement (appraisal) tool. The concept behind stack ranking is to rank all employees within a given statistical set, all first line supervisors for example, from best to worst. In its most common iterations managers rank, or stack, workers into one of the three groups. The highest performing 20% (sometimes 10%) are ranked as top performers. This top tier group of employees is considered to be the future leaders of the company. They are rewarded with bonuses, raises, promotions stock options and other perks. The middle 70% of the group are considered to be......
