Abstract

This paper presents a methodology that can be used for cost reduction of any product using the fundamental principles of Value Engineering. The paper specifically focuses on assembly called Arm Cross Bar (ACB) which is a sub-assembly of earth moving equipment called Wheel Loader. Wheel loader is a heavy equipment often used in construction and mining application, primarily used to transfer material from stockpiles to trucks, or transport material around job sites. Using value analysis tools, ACB was analysed and design alternatives were identified, that can reduce the weight as well as cost of the assembly without compromising the functional parameters. This will help the company to offer the product at a very competitive price. This will enhance customer delight, increase in sales of product and very importantly reduce the carbon foot print.

Keywords

Value Analysis (VA)/Value Engineering (VE), Wheel Loader (WL), Arm Cross Bar (ACB), Function Analysis System Technique (FAST).

Abstract

In the competitive market scenario, the companies are facing difficulties in making profit. The lean concepts are like solution tools for them. It mainly focuses on eliminating wastes from the process followed in the industries and creating valuable product to the customer with less capital investment. The Just in time (JIT) is an ideology originated in Toyota as like other lean concepts but it focuses on providing a pathway for the industries to reach a state where inventories requirement on the shop floor will be fulfilled by the suppliers at real time. The case study conducted in valve manufacturing industry where the raw material inventories have a larger pie of investment. The Sole purpose of this paper is to identify gaps present in supply chain process and replace it with JIT Approach. For identify the supply chain, understanding of procurement cycle is important. So, The Pathway starts with identification of key customer along with its key product. The key product is thoroughly analysed with ABC Analysis to determine the targeted part. The part suppliers are compared with their delivery date and quality produced by them in current process. The supplier development strategy generates different proposals, among which best four are selected. Among these four, supplier ranking need to be reformulated with increased number of factors for evaluating suppliers than Continuous inventory removal (CIR) Plan has formulated based on Continuous sampling plan used in sampling inspection and data's are analysed on cost aspect for this method. As the conclusion, the JIT implementation brings several favourable factors like reduction in inventory level, less investment required for running business.

Keywords

Just in Time, Continuous Inventory Removal, Predetermined Minimum Method.

Abstract

In this paper Value Stream Mapping (VSM) tool is used in valve manufacturing industry by focusing both on processes and their cycle times for a product 3/4 bonnet valve. In order to use the value stream mapping, relevant data has been collected and analyzed. After collecting the data customer need was identified. Current state map was draw by defining the resources and activities needed to manufacture, deliver the product. The study of current state map shows the areas for improvement and identifying the different types of wastes. In this Process (current state) it is noticeable that it is a batch flow and WIP is in the form of machine availability and customer demand time.

Keywords
