Abstract

This paper deals with minimization of the total elapsed time for nx3 flow shop scheduling problem. A Branch and Bound technique is given to optimize the objective. The algorithm defined in this paper is very simple and easy to understand and, also provide an important tool for decision makers to design a schedule. Our aim is to obtained optimal sequence of jobs and to minimize the total tardiness. The working of the algorithm has been illustrated by case study.

Keywords

Abstract

This paper evaluates inventory situation at Shivkumar Textiles Maharashtra Solapur. The objective of this paper is to develop the Economic Order Quantity (EOQ) model that will be used to determine number of units of an item to order at a time and the re-order point (r), that is the level to which stocks of items are allowed to fall before ordering other items, for raw materials. The resulting EOQ for each raw material is compared to the actual ordered quantities so as to see whether there is any relationship between them in operational cost reduction. The comparison of operational cost reduction was done by using normal distribution test. MS Excel was used to find EOQ and the re-order point. The results show that the relationship between the EOQs and the ordered quantities in terms of operational cost reduction was significant. Therefore, it was concluded that the ordered quantities at Shivkumar Textile mill were not optimal.
