ABSTRACT - Value Engineering is used to design the product that will represent the optimum value to the manufacturer and customer. Value Engineering is a systematic methodology for continuous improvement of products, process etc. The basic fundamental of Value Engineering can be implemented in any product to optimize its value for customer satisfaction by keeping same cost or by increasing the product cost to some extent with value addition. A computer work station manufactured in a furniture industry is taken for optimization of its value in which the product is designed by using value engineering concept. Existing computer work station consists of table top, base top (middle), base top (lower) base top (side), keyboard base, keyboard side strip, keyboard stopper, steel frame, slider, keyboard guide strip with rexin and stud. This product is modified with value addition by reducing length of keyboard and by adding one drawer with lock and key and removing the base top (lower), there by which some required material can be stored in the drawer safely. This drawer can be manufactured from waste cut pieces of board. Also the length of keyboard is reduced thereby which the cost is also reduced. Key words: Value Engineering, Value addition, Computer Work Station, Product Improvement, Furniture Industry. 1. INTRODUCTION Fundamentally, Value Engineering (VE) is a systematic process to improve the value of a product. VE began in the industrial sector in the 1940s and 50s, in the context of product design. Its beginnings are usually attributed to Lawrence Miles, who pioneered its use at General Electric in 1947. Since then, VE methods and applications have expanded significantly and have been applied in a wide variety of environments, from building construction to health care. Similar processes appear under analyzing the function and the cost of the object, the core is to analyze the function. ISSN: 2231-5381 several different names, including Value Analysis and Value Management. The Society of American Value Engineers International, or SAVE, uses the broad term “Value Methodology,” defined as “the systematic application of recognized techniques which identify the functions of the product or service, establish the worth of those functions, and provide the necessary functions to meet the required performance at the lowest overall cost.” A few descriptions of VE concepts are necessary to understand what is considered to be part of VE. First, the product under consideration: this product may be virtually anything; some examples are manufactured objects, buildings, management plans, and road segments. SAVE states that the Value Methodology, or what we shall call VE, “can beneficially be applied to virtually all areas of human endeavor,” “wherever cost and/or performance improvement is desired.” In the construction industry, VE is usually applied to individual projects at various points in their development, particularly between the design and construction phases. Next, it is important to understand what constitutes the value of the product, since “the main objective of VE is to improve value.” Several approaches have been proposed to define and measure “value.” Value Engineering is a directive significance way to the improvement of the products’ cost and function, and there are some disadvantages of the computer work station. Though there are researches on the improvement of the computer work station, we put emphasis on the aesthetic and design parameters. Through evaluating the improving program, we can see that the computer work station improved based on the Value Engineering can solve the disadvantage of material used, lacking of different sized material and design of product with value addition which also reduces the cost. Value Engineering is a technical and economic method which studies on how to achieve the necessary function with the lowest cost. The main idea of Value Engineering is to enhance the value of the object through 2. ABC Analysis in the Furniture Industry Every manufacturing firm requires allocation of raw materials consumption, labor, and overhead expenses http://www.ijettjournal.org Page 2846 International Journal of Engineering Trends and Technology (IJETT) - Volume4 Issue7- July 2013 to processed goods in order to determine the final manufacturing costs. In most industries, manufacturing costs range from 60 to 70 percent of the final sale price. Therefore, the need for effective cost allocation systems is vital to control manufacturing costs. In manufacturing firms such as the furniture industries, raw materials and labor might be assigned directly to a product, process, or activity. However, some overhead or indirect costs require the establishment of distributing or cost driving bases to allocate them to final goods. This publication was developed based on concerns from furniture producers that more training in cost accounting methods should be available for practitioners. The paper discusses the basics of cost accounting and explains the strengths and weaknesses of two cost accounting techniques — the direct method and the activity-based costing (ABC) method — using simple examples and applications in the furniture industry. Figure 1 ABC Analysis A class items which represent about 10-15% of the total parts count but account for 70% of the total product cost B Class items which represent the next 20% of the total parts count and the next 20% of the total product costs (for a total of 90% C Class items which represent 70% of the total items, but only about 10% of the total cost. 3. Classification of Product Cost Cost can be classified depending on the financial format used for reporting. For manufacturing companies, cost is usually reported based on product cost. Under this reporting format, the cost needs to be broken out into direct materials, direct labor, and overhead/indirect costs. Direct materials costs are directly linked to a product, activity, or process and sometimes are the largest portion of the total costs. Direct materials can be raw materials or subassemblies as well. Direct labor cost refers to all employees that worked in the manufacturing of a product; they can be allocated by activity, product, or process as well. Collecting direct labor cost information ISSN: 2231-5381 might require intensive use of information technologies, and these costs are a major driver for business strategy in value-added wood products industries such as the furniture industry, which is very labor intensive. All other manufacturing costs that cannot be classified or traced back to the product, activity, or process are considered “indirect costs” or “overhead”; these might include labor, materials, or supplies. Because overhead costs cannot be directly allocated to a product, activity, or process, a cost driver is needed to allocate the cost into a “cost pool.” A cost pool is a collection of indirect costs assigned to a cost object (machine hours, units produced, etc.). Some examples of indirect costs/overhead in a wood products industry include glue, paint, sandpaper, tooling, electricity, hardware, insurance, water, administrative salaries, and energy. 4. Computer Work Stations Figure 2 Computer Work Station (Existing) Model No.: CWS-1002 Figure 3 Computer Work Station (Proposed) Model No.: CWS-1009 5. Value Engineering Analysis of the Computer Work Station http://www.ijettjournal.org Page 2847 International Journal of Engineering Trends and Technology (IJETT) - Volume4 Issue7- July 2013 1. Distribution of cost The Existing computer work station consists of table top, base top (middle), base top (lower) base top (side), keyboard base, keyboard side strip, keyboard stopper, steel frame, slider, keyboard guide strip with rexin and stud. Existing computer work station is modified by reducing length of keyboard and by adding one drawer with lock and key and removing the base top (lower). There by which some material can be stored in the drawer safely. This drawer can be manufactured from waste cut pieces of board. Also the length of the keyboard is reduced thereby which the cost is also reduced. According to the principle of classification, if cumulative proportion of total costs of the component is between 60%-70%, the component is classified as the A classification, if it is between 15%-20%, the component is classified as the B classification, and if it is near 10%, the component is classified as the C classification. 2. Analyzing of function The basic function of the computer work station is to hold the all parts computer system, and the secondary function is easy to handle, durable and with a beautiful appearance. Through analysis of function of each component, we define the function of table top is to support the computer, base top (middle) is to support the printer and UPS, base top (side) is to support the CPU, keyboard base is to support keyboard, keyboard side strip is to hold slider, keyboard stopper is to restrict extra movement, steel frame is to hold top, the function of slider is to hold keyboard, keyboard guide strip with rexin is to provide comfort, drawer is to hold the material and stud is to support weight and leveling. The function definition of computer work station’ component is shown in table no.2. 3. Functional evaluation 3.1 Defining the functional coefficient (1) Defining functional importance coefficient: Calculating the importance coefficient using absolute evaluation method which asks 6 operators to grade for each function. Sum up the grade of each function given by the 6 operators, and then calculate the importance coefficient using the total grade of each function given by the 6 operators to divide by the total grade of the computer work station. The grade given by operators and the result of calculating the functional importance coefficient are just like table no.1 shown. From the result, we can see that functional importance coefficient of support the computer is 31.17%, functional importance coefficient of easy to handle is 21.16%, functional importance coefficient of durable is 23%, functional importance coefficient of beautiful appearance is 15% and Fictional importance coefficient of hold other material is 9.16% (2) Calculating the functional evaluation coefficient of key components. Asks 6 operators to grade for each function of each component, the total grade of each function is 100, which is shown in table no.1. Then calculate the functional coefficient of each component shown in table no.3 by ISSN: 2231-5381 multiplying functional importance coefficient which is shown in table no.1 and the functional proportion coefficient which is shown in table no.2. From the result we can see that functional evaluation coefficient of Steel Frame, Table Top, Drawer with Lock & Key, Keyboard base, Base Top (Middle), Base Top (Side), Keyboard side strip, Slider, Stud, Keyboard guide strip with rexin, Keyboard stopper is 0.2901, 0.2476, 0.1358, 0.0763, 0.03538, 0.05518, 0.0075, 0.0653, 0.0453, 0.0225 and 0.018. 3.2 Defining the cost coefficient Calculating the cost coefficient of the 11 key components according to their current cost, the result is shown in table no.6. From the result we can see that the cost coefficient of Steel Frame, Table Top, Drawer with Lock & Key, Keyboard base, Base Top (Middle), Base Top (Side), Keyboard side strip, Slider, Stud, Keyboard guide strip with rexin, Keyboard stopper is 0.3961, 0.1927, 0.1784, 0.0499, 0.0535, 0.0364, 0.0356, 0.0356, 0.0085, 0.0071 and 0.0057. 3.3 Calculating the value coefficient The 11 key components’ value coefficient can be calculated according to functional evaluation coefficient table (table no.5) and cost coefficient table (table no.6), which as table 5.15 shown, in order to determine the target of improvement. The value coefficient of Steel Frame, Table Top, Drawer with Lock & Key, Keyboard base, Base Top (Middle), Base Top (Side), Keyboard side strip, Slider, Stud, Keyboard guide strip with rexin, Keyboard stopper is 0.7323, 1.2848, 0.7612, 1.5290, 0.6613, 1.5159, 0.2106, 1.8342, 5.3294, 3.1690 and 3.1578. So the order of the components to be improved is keyboard side strip, base top (middle),steel frame, Drawer with lock and key, table top, base top (side), keyboard base, slider, keyboard stopper, keyboard guide strip with rexin and finally stud, 3.4 Result of value Analysis According to the value coefficient of the 11 key components shown in table no.7, we can come to a conclusion: (1) Drawer with lock and key, Keyboard side strip, Steel frame, and Base top (middle) are the main components need to be improved, for their value coefficients are less than 1, which means the function are too less or the cost are too much. (2) Table top, Keyboard base, base top (side) and slider need not to be improved for their value coefficients are close to 1 which means the function and the cost are nearly the same. (3) The coefficients of Keyboard stopper, keyboard guide strip with rexin and stud are more than 1, which means the cost is already lower compared with function that has already met the needs. And in this condition, Base top (Side), slider, keyboard guide strip with rexin and stud are not the target of value analysis, we may neglect the analysis of them. http://www.ijettjournal.org Page 2848 International Journal of Engineering Trends and Technology (IJETT) - Volume4 Issue7- July 2013 Table-1 ABC Analysis of the Computer Work Station Name of Component Proportion of the Total No. Qty.

Conclusion The value engineering analysis suggests that the existing Computer work station can be modified in to proposed computer work station by adding one drawer with lock and key and removing the base top (lower) by which the customer requirements are can be fulfilled. Cost analysis of the existing computer work station (Rs.1194.00) and proposed Computer work station (Rs.1401.00) shows that the cost is increasing by Rs. 207.00 but in the proposed computer work station we have added one drawer which can be manufactured by using waste cut pieces therefore only lock and fitting screws are required which costs Rs. 30.00. Therefore the cost of drawer can be reduced from Rs 250.00 to Rs. 30.00 as it is manufactured from waste cut pieces. Also in the proposed computer work station, the base top (lower) is also removed with reducing the size of the keyboard base in which the material saving is achieved. The total cost of proposed computer work station can be reduced from Rs. 1401.00 to Rs. 1181.00. Comparing this with existing computer work station, we achieved the cost saving of Rs.13.00 with Value addition by adding one drawer with lock and key in the proposed computer work station. 7.
