Implementation of Material Requirement Planning (MRP) on Raw Material Order Planning System for Garment Industry

Abstract

The increasingly competitive business environment has encouraged many actors to use information and communication technology as a competitive advantage, including the garment industry. So far, difficulties in controlling raw material inventories which causes problems for the production process. If there is a shortage of raw materials, the production process cannot be carried out, on the contrary if the raw material ordered is too excessive it will cause excess and the high cost of raw material inventory. This research develops an information system that can plan the needs of raw materials needed for production. This system is web-based, applying the MRP (Material Requirement Planning) method to develop raw material ordering planning systems, case studies at garment companies, using PHP programming and FIREBIRD databases. This system gets input from the production schedule resulting from production scheduling information system, then provides output in the form of recommendations for scheduling raw material orders. This output can later be used as a reference for the company’s operational decisions in planning raw material requirements.

Model to increase the use of production capacity using Lean tools in the paint subsector

“…Therefore, they propose, mainly, the improvement based on an improved aggregate planning method through the use of a system that allows to keep track of the inventories of raw materials and inputs, and this way estimate the quantities to be requested for future requirements; obtaining an 80% reduction of the planning errors of raw material orders and also reduce by 41% the delivery times of these finally increasing up to 87.5% of the company's productivity. [5] Finally, another success story that is identified very similar to the current situation of our case study is that of the authors study and analysis of the performance of the suppliers of a production company that constantly presents breaks in the deliveries of their requested request orders in an anticipated period to avoid delays or stock breaks. However, 60% of its suppliers miss their delivery dates.…”

“…The Material Requirements Planning it is defined as a technique that allows to determine the quantity and time of purchase of articles of demand necessary to satisfy the needs of the Master Program of Production [18], which was also designed to support the manufacturing industries in the management of inventories with dependent orders and programs the replenishment of materials. Even some authors such as Kholil et al, 2019 mention that this tool provides us with reliable and accurate results for the correct replenishment of raw materials and inputs and maintains optimal safety stock levels so that it does not generate many maintenance costs or stock breaks that could lead to production stops.…”

A Development and Implementation of Manufacturing Resource Planning System for Small and Medium Enterprises

“…Hasanati, Permatasari, Nurhasanah and Hidayat [10] divided the development of MRP into three distinct realms to describe it. In the first realm, MPS goods are generally completed, made-to-stock products; MPS is defined based on projected item demand deciphered to a succession of manufacturing systems through staged arrangements or regulations.…”

Analysis of raw material inventory for insecticide packaging bottle with material requirement planning: a case study

“…Research with the MRP method has been widely used in various industries, for example apparel [6], paper [11], cement [12], automobile [13], garment [15], construction [16], motorcycle chains [17], talc powder [18], screen printing ink [19], briquette [20], sewing thread [21], pharmaceuticals [22], alloy cast [23], and coconut sugar [24]. The majority of existing research discusses the raw materials for making finished products.…”

“…Material Requirement Planning is a method for carrying out production planning to determine the order date and quantity of materials ordered to fill each product component [13], [14]. MRP system also provides appropriate information about inventory and production [15], [16]. Material Requirements Planning aims to schedule raw materials, components, and sub-assemblies quantified in the correct quantity and ready at the right time [17], [18].…”
