This paper examines manufacturing planning within small-batch make-to-order. Electronic equipment manufacturing companies face challenges caused by increasing numbers of product variants as the demand for individualized products rises. Enterprises have to provide more individualized products instead of standardized ones. Cause of high variation in volumes and high mix of products it is difficult to use common planning tools. Known manufacturing planning methods cannot quickly realize adaptation for efficient use of enterprise capacities. This problem became big challenge for production planners. The purpose of this paper is to understand the requirements on enterprises to use planning and scheduling in small batch make-to-order production. We explore challenges associated with planning strategies. Finally, we consider a functional model of developing a planning system.

Efficient use of production capacity is an important complex of engineering tasks. Faced with the need to modernize production in the face of high competition and changing customer needs, company owners are forced to test new engineering solutions. Maximizing the existing production capacity plays a fundamental role in maintaining competitiveness and improving the efficiency of resource use in the production of electronic equipment. Electronic equipment manufacturing uses a make-to-order strategy and has a large number of variants of the product in a very small batch. But it is a problem of implementing the standard solution for efficient use of production capacities. Using simulation methods allows one to make informed decisions on using planning and scheduling in small-batch make-to-order production. We describe the process of developing a simulation model of the assembly shop of electronic production using Tecnomatix Plant Simulation software. The focus is on the search for the optimal capacity utilization of the workshop. The created model allows getting detailed statistics about various aspects of functioning of the workshop, depending on the input data.

The structural-dynamic approach to the formalization of the information exchange objects structure and behavior under Integrated Information Environment is considered: electronic design document and a typical design object. For the objects formalization and modeling the basic of subject-oriented ontologies, automata and set theory were used. The subject area (scope) and the electronic design document structure is formalized in ontology. Graphic representation of the information exchange objects life cycle performed as colored oriented nets. The ontological approach and colored networks allows revealing the relationship between structure and behavior of information objects, avoiding information inconsistency of complex multiply connected structures. The proposed approach provides an opportunity to take into attention the entirety of electronic design documents submission and design objects, which is difficult to ensure using alternative modeling methods.
