Abstract

Most companies nowadays are organized into networks of manufacturing and distribution sites that procure raw materials, process them into finished goods, and distribute the finished goods to customers. The goal is to deliver the right product to the right place at the right time for the right price. This production - distribution network is what we call "supply chains. After years of focusing on reduction in manufacturing and operating costs , companies are beginning to look into transportation costs to further reduce the costs. In the present paper an integrated view of the supply chain has been proposed. The proposed model takes into consideration the manufacturing, inventory and distribution costs involved in a supply chain consisting of multiple plants, multiple warehouses producing different products and supplying to different customers with different demands for the finished product. The proposed model is formulated to minimise the total cost of the supply chain.

Abstract

Inventory management is very important area in the supply chain management. Excess stocks may lead to incurring holding costs while shortage of stocks lead to shortage costs. The problem becomes more complicated when several factories produce multiple products in multiple time periods and supplies to several distribution centers who in turn supply to various agents and customers. With the advances in information technology and computing methods the inventory management problem in a multi echelon supply chain can be solved reasonably well. This paper presents an approach for the multi product inventory optimization in a multi echelon supply chain using Artificial Bee Colony Optimization method.

Keywords

Abstract

This paper presents an experimental investigation aimed at identifying and isolating effects of cutting conditions and over hanging length of work piece and over hanging length of tool on cutting forces and vibrations from those arising as a result of cutting tool wear. Machining test cuts were conducted using sharp tool and the effects of cutting conditions (depth of cut, cutting speed and feed rate), tool overhanging length and work piece over hanging length studied. Here experiments were conducted on EN8 steel, EN24 Steel, Mild steel and Aluminium at different cutting parameters and different overhanging lengths. Here chatter starting point length is measured from the free edge of the work piece and graphs were plotted between over hanging length verses cutting forces and chatter starting point length.
