Calculation Analysis

The article deals with issues surrounding the production management of enterprise with small-series production type. Specific features of small-series production are determined. Task complex defined by initial production phase comes under review. Problem of calculation, analysis and optimization of machine load is covered in depth. It is assumed that machine load calculating task will minimize potencial stress of production plan and maximize workplace capacity. Calculations are carried out for each type of work for the required period (year, month, week, etc.) for the whole enterprise, workshops, production areas, workplaces. The labor intensity for each workplace and usage coefficient are calculated. The analysis of obtained indexes is the basis for redistribution of the workload capacity.

Component Quality

Die additive Fertigung schafft neue Gestaltungsfreiheiten. Im Rahmen des Prototypenbaus und der Kleinserienproduktion kann das Verfahren des selektiven Laserschmelzens genutzt werden. Die Verwendung in der Serienproduktion ist bisher aufgrund unzureichender Bauteilqualität, langen Anlaufzeiten sowie mangelnder Automatisierung nicht im wirtschaftlichen Rahmen möglich. Das Projekt „ReAddi“ möchte eine erste prototypische Serienfertigung entwickeln, mit der additiv gefertigte Bauteile für die Automobilindustrie wirtschaftlich produziert werden können. Additive manufacturing (AM) offers new freedom of design. The selective laser-powderbed fusion (L-PBF) process can be used for prototyping and small series production. So far, it has not been economical to use it on a production scale due to insufficient component quality, long start-up times and a lack of automation. The project ReAddi aims to develop a first prototype series production to cost-effectively manufacture 3D-printed components for the automotive industry.

Production: A Neglected Area of Management

Huge Investment

Production management is one of the most neglected areas in India. This is surprising, considering India's huge investment on machinery for increasing production and ample trained engineers who are reluctant to enter production areas in view of inadequate returns for the hard work they put in. A better understanding by top management of the problems faced by production people coupled with adequate compensation and perquisites will go a long way in attracting the cream of the country's youth to production management.

The task of drawing up an optimal production plan for an enterprise with limited resources and problem solution of bridging production bottlenecks for only one enterprise are of limited interest. New technical capabilities due to the volume and speed of data transmission and processing, allow you to solve new problems in which the apparatus of the duality theory can be fully used.The authors consider the problem of planning the optimal production company (firm, industry, ministry) volume, which structurally has a certain coordinating (managing) center and a network of enterprises (branches), which can be located in different regions, and are not connected with each other. Each of the branches has its own technological matrix of resource costs for output, resource reserves, expected profit from the sale of each type of product unit.An iterative algorithm for finding production plans for each of the enterprises is proposed, when implementing which the total profit of the company can be increased. The Center finds the optimal production plan for each of the enterprises according to this algorithm and using the classical formula of the optimal production planning problem. Further, for each of them, the Center, solving the problem of resolving production bottlenecks for each of the enterprise, determines the supply volumes of resources scarce. The Center supplies scarce resources to enterprises and forms a new adjusted output plan for each of the enterprises. If it is impossible to supply scarce resources to meet the needs of all enterprises in the company, the options for the most promising planning models are offered, under which the total profit of all enterprises in the company will be the greatest.The implementation of the planning scenarios proposed below becomes real when switching to digital production management methods.
