Design and Fabrication of Trammel Balls
Abstract: Transportation of water plays a vital role in the survival of a growing population. If the scarcity of water is one major issue, transportation of water using tankers have their own share. Water in a partially filled container, when induced with external energy (motion), generates slosh and surge. Both slosh and surge effects work as a resistive factor during transportation. To eliminate the same, few holes are drilled at pre-desired …

Lean Manufacturing
Abstract: An important goal of lean manufacturing is to speed up response times from suppliers and consumers as well as times spent in the production system. It has a tight relationship to another idea known as just-in-time manufacturing (JIT manufacturing in short). Just-in-time manufacturing prioritises productivity, effectiveness, and waste reduction for the producer and supplier of goods in an effort to match output to demand by only supplying items that have …

Optimizing Work Scheduling In Shop Floor Using Ant-Colony Algorithm
Abstract: A job shop manufacturing system is specifically designed to simultaneously produce different types of products in a shop floor. Job shop scheduling problems (JSSPs) have been studied extensively and most instances of JSSP are NP-hard, which implies that there is no polynomial time algorithm to solve them. As a result, many approximation methods have been explored to find near-optimal solutions within reasonable computational efforts. Furthermore, in a real world, JSSP …
