Abstract

The Pump Industry is characterized by steady growth in periods of economic growth and decline when capital investments are down in high interest rate periods. The demand for pump components can be predicted with some degree of accuracy when scientific tools of inventory management are deployed. These tools help reduce needless inventory levels and lower capital expenses for firms at times when the interest rate and hence cost of capital is high. The aim of this project was to reduce the cost of inventory of items selected by 10 percent points. The items selected were grouped into a two by two matrix, popularly known as Kraljic’s matrix. The items were classified on the basis of whether the spend was high or low and whether supplier vulnerability was high or low. The Quantity price break model was used for items which were low in spends and low in supplier vulnerability. The EOQ model was deployed where the Spend was high and the supplier vulnerability was low. The complete aggregation model was applied where the Spend was low and the Supplier Vulnerability was high and the Taylor aggregation was used when both Spends and Supplier Vulnerability was high. Demand data from April 2012 to March 2013 was used to process information. In addition, procurement and transportation cost was also obtained for each product selected for the analysis. Results showed 25% savings from the EOQ model for rotor shaft respectively. The quantity discount model revealed 3.08% savings potential. Similarly, 9.7% savings for complete aggregation model in security segment and 11.47% saving for tailored aggregation model in critical segment have been attained. In summary, reduction in inventory cost of 13% has been obtained across all the models. Future studies can be carried for other categories of materials in the submersible pump industry.

INTRODUCTION

The purpose of the project is to make a study about Deccan Pumps Pvt. Ltd and understand the inventory management in pump manufacturing sectors of the company, calculate the efficiencies of pump industries, find out challenges and find out solution for deficiencies and the challenges. The academic project is undertaken to carry out and to study of reduction in inventory of bore well submersible pumps industry. This project has got support from Deccan Pumps Pvt. Ltd Coimbatore.
Deccan Pumps Pvt. Ltd has been synonymous with revolutionizing India’s traditional pump manufacturing industry. The industry was started in the year 1981 with the first exclusive production line for submersible pump sets in the country. Then food sufficiency was the major focus of the Indian government. ‘Food sufficiency through ‘green revolution was made possible because of the installation of large quantity of pump sets, especially the bore well submersible pump sets.
India’s economy is based mainly on agriculture and it is the back bone of the country. India’s agriculture depends upon the timely monsoon and amount of rainfall in any year. To avoid uncertainly of monsoon, farmers in India resort to various methods of irrigation. India, being a vast country with a high variation in geographical conditions needs several irrigation techniques.
In areas of shallow water levels (1-6 meters head) axial flow or mixed flow pumps are used to lift water. Where water levels are at (6-40 meters head), mostly radial flow pumps are used. For deep bore wells submersible pumps or compressor are used depending on the head and discharge requirements and on the availability of water in the bore well.
A. Pump Indu stry in India
The first electric motor in India was manufactured in Coimbatore in 1930 and thereafter the motor pump industry expanded rapidly. Today 60% of India’s requirements of domestic and agricultural pump sets are made in Coimbatore. The southern India engineering manufacturers association (SIEMA)(established in 1952) has 215 members, manufacturing motors and pumps of various types. Indian pumps are made according to the specifications of the Bureau of Indian standard (BIS), Coimbatore.
Inventory management
Control of inventory, which typically represents 45% to 90% of all expenses for business, is needed to ensure that the business has the right goods on hand to avoid stockouts, to prevent shrinkage and to provide proper accounting. Many businesses have too much of their limited resource, capital, tied up in their major asset, inventory. They may be an imbalance among different product lines that reduces the customer appeal of the total operation.
Inventory control system can give to the range to eyeball system to reserve stock systems to computer-run systems. Valuation of inventory is normally stated at original cost, market value, or current replacement costs, whichever is lowest. This practice is used because it minimizes the possibility of overstating assets. Inventory valuation and appropriate accounting practices.
The ideal inventory and proper merchandise turnover will vary from one market to another. Minimum inventories based on reordering time need to become important aspect of buying activity. Carrying costs, material purchases and storage costs are all expensive. However, stock outs are expensive also. All of those costs can be minimized by efficient inventory polices.
Inventory control involves the procurement, care and disposition of materials. There are kinds of inventory that are of concern to managers, raw material, in process or semi finished goods, finished goods. If a manager effectively controls these types of inventory, capital can be released that may be tied up in unnecessary inventory, production control can be improved and can protect against deterioration.

PROBLEM DEFINITION

The study has attempted to reduce the inventory of raw material at a leading company in the pump industry. An analysis has been done on current trends of the order quantity and prices of the operation. The production level, inventory level and capacity level have been determined for each period that maximizes the firm profit.
