CASE STUDY OF THE CLEAN DISH COMPANY’S NEW MODELS PRODUCTION INTRODUCTION Clean Dish is an Australian company with its headquarters in the city of Perth specializes in the production of dish washers for distribution within Perth and across the country. The company plans on introducing new models of dish washers with improved technology into the market as a counter to competitors’ recent models. The release of the new models will help the company keep up with other companies producing dish washers in Australia, in terms of technology, competition and market share. Companies are constantly under pressure of releasing new models. This pressure comes from either the consumers or the competitors, or both. For industries such as the smartphone industry, pressure primarily comes from the consumers who expect new phone models after given periods of time(O'Malley & Lichrou, 2016).The competition from other firms also compounds this pressure. However, in other industries such as the dish washer industry, where the Clean Dish operates, the source of pressure is mainly competitors rather than the consumers. Products that are not easily differentiable spur the pressure for competitors to produce new models(Kotler, 2009). This can only be achieved through continuous innovation, and preferably disruptiveinnovation, to create the product differentiation. The production and eventual release of disruptive innovations is however a costly undertaking, especially in terms of the cost of raw materials, in addition to the market risks, there is no guarantee that the consumers will like and purchase the product(Farris & Neil, 2010). Thus, there is need to ensure that such risksare significantly reduced while still allowing for the launch of the product. In order to reduce risks, companies can apply linear programming for new product releases. Linear programming is a mathematical method used in statistical analyses of the 3
CASE STUDY OF THE CLEAN DISH COMPANY’S NEW MODELS PRODUCTION optimal utilization of input variables, optimal outcomes of processes and quality control of processes and outputs(Hastie, Tibshir, & Jerome, 2009). Linear programming is an efficient statistical tool for companies that are interested in launching new products or new models into the market(Besanko, Dranove, & Shanley, 2012). It assists in determining the amountof raw materials to be committed, production margins as well as expected profits or losses. This study focuses on the application of linear programming methods for the case of the Clean Dish company. The method will be used to advice on the production of the two new models of dish washers that the company plans to introduce into the market. PROBLEM DEFINITION The continuous development of new technology in the dish washer industry has resulted in pressure in the industry for the production of new models. Clean Dish has developed new technology for its two new models of dish washers; Ultra Clean 1.0 and Ultra Clean 2.0. The company is however faced with the challenge of determining the exact number of each of the dish washer models for the premier phrase of production. Clean Dish has set up a new station specifically for the production of Ultra Clean 1.0 and Ultra Clean 2.0 models of dish washer machines. The company is however not ready to commit a lot of resources into the production lines for the two models until product market entry statistics are collected. Therefore, there is need to develop a strategy for the efficient utilization of the resources provided for the premier phrase of the production of the Ultra Clean 1.0 and Ultra Clean 2.0 models. 4

CASE STUDY OF THE CLEAN DISH COMPANY’S NEW MODELS PRODUCTION The development of an optimal resource utilization strategy will enable for the successful production of the Ultra Clean 1.0 and Ultra Clean 2.0 models without the company suffering additional costs from engaging additional resources to the new station for the production of the models. The optimal resource utilization strategy will also allow for the estimation of the maximum possible profits given the resources available to the new station. MODEL DESIGN FORMULATION OF LINEAR PROGRAMMING PROBLEM The resources that Clean Dish has made available to the new station for the production lines for Ultra Clean 1.0 and Ultra Clean 2.0 models are as follows; 100 containment units, 720 square meters of insulation and lining material (polyurethane) and 1566 man-hours (hours of available labor for production period). Production of each unit of either of the models requires a single containment unit. The production of each Ultra Clean 1.0 model dish washer requires 3 square meters of insulation and lining material and 9 man-hours while the production of each Ultra Clean 2.0 model dish washer requires 4 square meters of insulation and lining material and 6 man-hours. The Clean Dish company has estimated the profit from one Ultra Clean 1.0 model sold as $175 while the estimated profit from one Ultra Clean 2.0 model sold as $150. The table below,Table 1: Linear Programming Summary for Clean Dish company, gives the summary of the formulation of the linear programming problem for Clean Dish new dish washer models. 5

CASE STUDY OF THE CLEAN DISH COMPANY’S NEW MODELS PRODUCTION RESULTS The results of the analysis in bothTable 2: Sensitivity Analysis ReportandTable 3: Linear Programming Outputindicate that: the optimal unit production for the Ultra 1.0 model is 65 units while the optimal unit production for Ultra 2.0 model is 35 units. This results in an estimated total profit of $16625. The tables also indicate that the number of containment units utilized will be 100, that is to imply that all the containment units will be used for the premier phrase of production. 335 square meters of thePolyurethane (insulation and lining material) will be utilized, out of the 720 square meters available for the premier phrase of production. Also, only 795 of the 1566 man- hours available will be utilized for the premier phrase of production of the two new models. RECOMMENDATIONS AND CONCLUSIONS The linear programming analyses of the linear programming problem for Clean Dish’s new dish washer models provide the following recommendations for ensuring reduced risks and successful premier phrase of production of the models: Clean Dish should produce 65 units of Ultra 1.0 dish washer model and 35 units of Ultra 2.0 dish washer model. The company should also reduce the resource allocation towards man-hours andPolyurethane (insulation and lining material) and instead increase the number of containment units to allow for the margin of error in the production process. 9
