Decision Support System For Production Research Articles

Production decision support system for multi-product with multiple different size processors

Aggregate planning is an operational activity with the objective of providing upfront information on quantity of material to be procured and resources to be secured. At a point of time, it might also influence both demand and supply. This is where the sales division will work closely with operation on aggregate planning to deliver maximum profit. Aggregate planning does not only serve as a master plan for the production planner, it is also closely linked to organisational decision-making. Realising its importance, researchers have worked on this subject consistently since 1950s but due to complexity and practicality issue, industry did not manage somehow to adopt the research work. In 2016, the concept of Production Decision Support System (PDSS) was introduced following the Pinch Analysis extended into supply chain area. In this work, the PDSS is applied to a batch industry case which involve multi-products with multiple different size processors. From the assessment, the PDSS has not only demonstrated its practicality but also helped the plant to realise their potential capacity. This has assisted the plant management to realign the strategy and avoided the original intention of expensive expansion.

Production Decision Support System: Real-life Emulsion Plant Case Study

As the world becomes increasingly globalised, chemical manufacturers have to make timely decisions and right strategies in order to stay competitive in marketplace. Numerous formal techniques have been suggested for aggregate planning but industry finds these models complicated and lack practicality. The objective of this paper is to develop an industry adoptable Production Decision Support System (PDSS) for multi-product and multiprocessor batch industries. The construction of this system is initiated with the development of a general batch production planning framework which will be eventually translated into an algorithm tool. This tool will be able to support the investigation of required sales forecasts against plant capacity by providing a complete overview with different scenarios on multi-product batch processes, thus improving effectiveness and efficiency of operational decision-making, as well as assisting in strategy establishment. The production contributory factors that are being considered for plant capacity include cycle time, batch size, plant availability, number of production lines and product mixes. The practicality and beneficial use of this PDSS system is then demonstrated through a real-life emulsion plant where its production capacity has been successfully stretched giving additional volume which has translated into additional revenue of RM 10 M to the company.

Production decision support system for computerized manufacturing systems

The introduction of Computerized Manufacturing Systems (CMS) into the mid-volume manufacturing industry has been an important new step in the development of automated manufacturing. CMS's are computer-integrated systems which incorporate Direct Numerical Control (DNC) capabilities with automatic material handling to manufacture parts. Due to its complex nature, the task of production control in an CMS cannot rely on human effort alone. It is essential to develop a software package in the form of a Production Decision Support System (PDSS) to assist the production decision maker in operating this complex manufacturing facility.
