used by operations managers and other managers to obtain optimal solutions to problems that involve restrictions or limitations‚ such as the available materials‚ budgets‚ and labour and machine time. These problems are referred to as constrained optimization problems. There are numerous examples of linear programming applications to such problems‚ including: • Establishing locations for emergency equipment and personnel that will minimize response time •

20 CHAPTER 3 NEW ALTERNATE METHODS OF TRANSPORTATION PROBLEM 3.1 Introduction The transportation problem and cycle canceling methods are classical in optimization. The usual attributions are to the 1940’s and later. However‚ Tolsto (1930) was a pioneer in operations research and hence wrote a book on transportation planning which was published by the National Commissariat of Transportation of the Soviet Union‚ an article called Methods of ending the minimal total kilometrage in cargo-transportation

hourly production of automobiles at 58 2 if the model were based upon average hourly production‚ and the production had the interpretation of production rates. At other times‚ however‚ fractional solutions are not realistic‚ and we must consider the optimization problem: n Maximize j=1 cjxj‚ subject to: n j=1 ai j x j = bi xj ≥ 0 x j integer (i = 1‚ 2‚ . . . ‚ m)‚ ( j = 1‚ 2‚ . . . ‚ n)‚ (for some or all j = 1‚ 2‚ . . . ‚ n). This problem is called the (linear) integer-programming

to represent the character candidates. The estimation of feature space parameters is embedded in HMM training stage together with the estimation of the HMM model parameters. Finally‚ the lexicon information and HMM ranks are combined in a graph optimization problem for word-level recognition. This method corrects most of the errors produced by segmentation and HMM ranking stages by maximizing an information measure in an efficient graph search algorithm. The experiments in dicate higher recognition

military operations. In essence you can state that OR is a technique that helps achieve best (optimum) results under the given set of limited resources. Over the years‚ OR has been adapted and used very much in the manufacturing sector towards optimization of resources. That is to use minimum resources to achieve maximum output or profit or revenue. Learning Objectives The learning objectives in this unit are 1. To formulate a Linear programming problem (LPP) from set of statements. 2. To solve

Duality in Linear Programming 4 In the preceding chapter on sensitivity analysis‚ we saw that the shadow-price interpretation of the optimal simplex multipliers is a very useful concept. First‚ these shadow prices give us directly the marginal worth of an additional unit of any of the resources. Second‚ when an activity is ‘‘priced out’’ using these shadow prices‚ the opportunity cost of allocating resources to that activity relative to other activities is determined.
