Representation and System Management of Logistic Objects
Published in Paul Schönsleben, Integral Logistics Management, 2018
In principle, all types of order position may appear in sales, production, and procurement orders. Sales orders generally relate to item issues, although in service companies they may also involve work and the production equipment used.Procurement orders generally contain item receipts, although purchased services can also involve the work and equipment types.Production orders are more complicated from the viewpoint of a firm’s logistics: There is often only one item receipt, that is, the manufactured and salable product. This goes either into store or to shipping and thus is passed on to the sales department, which placed the order. In other situations, the item receipt is a semifinished good that is placed in stock. It is also possible for several different item receipts to arise from the same production process (see Chapter 8).From the logistics viewpoint, the commodities used in the production process are also item issues; for example, issues from the raw materials or semifinished goods store. A production order is characterized by operations and the production equipment used, that is, tools, devices, and machines.

The core process supported by the production module is the production order process. This process uses production orders to manage the activities in the production. The production order process includes production planning, picking the required raw materials and components, reporting the progress on the shop floor, and so on until the finish items are put into stock and the financial account is updated.

Despite their simple statements, these decisions are often hard to make, since the department in charge is disconnected from the real progress of the shop floor. The decision taken becomes unsuitable because it is taken based on non-contextual observations or theoretical recommendations. To make the right decisions, management staff must be able to efficiently exploit all available information. Three levels of decision-making (operational, tactical, and strategic) are identified in the enterprise. Several information systems are available in the company to support information management and exchange at each decision-making level. For instance, ERP (Enterprise Resource Planning) and PLM (Product Lifecycle Management) form the core of the information system. The execution of production orders are managed by a Manufacturing Execution System (MES).

One production task may contain one or more production orders, which are composed of a wide range of workpieces. When each production order is placed, its priority has been preliminarily determined. Normal orders are represented by ‘0’, and urgent orders are represented by ‘1’. In the case of the same priority, the WIP is processed by using the first-come-first-served principle. In the case of the urgent orders, the WIP can be machined first. During the production process, if a normal order is upgraded to an urgent order, its corresponding priority value will change from ‘0’ to ‘1’. WIP in the input buffer will be transported to the machine tool for processing by the robot priorly. WIP in the output buffer will be transported priorly to the warehouse by AGV for packaging and storage. The quantity of each type of workpiece and its corresponding priority value compose the production task. Therefore, the production task is described as follows: where is the quantity of the workpiece , is the priority value of the workpiece . Production data composition
Optimised scheduling in human–robot collaboration – a use case in the assembly of printed circuit boards

This section will cover an extension of the case where, instead of just one board, an entire sequence of different boards, each of them with individual specifications, is to be produced. This setting is highly relevant for low volume production where single boards are considered in the planning process and the contribution of human workers is still significant. Clearly, for high volume production orders, classical batch processing strategies and a higher level of automation are implemented. We will first explain the set-up of the production process before discussing the necessary adaptations of the ILP model.
