Abstract
Efficient order execution plays a crucial role in the activity of every company. In production planning it is important to find a balance between the fluctuations of orders and stability of production flow regarding the company. One of the methods of achieving this goal is heijunka (production leveling). This paper presents a study of choosing the best variant of the production planning and control system for the production of standard parts. Three variants are investigated regarding delays in order delivery. The analysis of variants was conducted using a simulation method. The method of choosing the best variant for the production system being investigated is also proposed. The results show that the best variant is a mix of production leveling and production "for stock".
Highlights
In the era of constantly growing competition and a clear increase in customer requirements, production companies are trying to adapt to the changing economic conditions as muchas possible
Due to the increase in costs, many companies decide to market products in accordance with the concept of an assemble-to-order system, which provides customizable final products composed of standard parts that can be produced in a serial way
In criterion B, the most orders were delivered on time in variant 3 (713 orders completed on time), while the least in variant 1 (474 orders completed on time)
Summary
In the era of constantly growing competition and a clear increase in customer requirements, production companies are trying to adapt to the changing economic conditions as muchas possible. Others decide to manufacture individualized (customized) products that meet today’s customer requirements [2]. It is important to deliver products tailored to individual requirements or customer concepts. This strategy entails a number of problems related to the increase in the costs of product design and production [3]. Due to the increase in costs, many companies decide to market products in accordance with the concept of an assemble-to-order system, which provides customizable final products composed of standard parts that can be produced in a serial way. One of the many threats caused by this type of production are the constant changes in production plans for the components included in the finished product, dictated by changing orders for final products, or uneven inventory levels, as well as the load on machines [4, 5]
