It also discusses consumption and production of products, as well as the necessary operations on machinery, tools or human resources.* Manufacturing management in OpenERP is based on its stock management and equally very flexible in both its operations and its financial control. It particularly benefits from the use of double-entry stock management for production orders. .. index:: single: module; mrp Manufacturing management is implemented by the :mod:`mrp` module. It is used to transform all kinds of products: * Assemblies of parts: composite products, soldered or welded products, assemblies, packs, * Machined parts: machining, cutting, planing, * Foundries: clamping, heating, * Mixtures: mixing, chemical processes, distillation. You will work in two areas: with products in the first part of this chapter, and with operations in the second part. The management of products depends on the concept of classifications while operations management is related to routing and workcenters. .. index:: single: bill of materials .. note:: Bills of Materials Bills of Materials, or manufacturing specifications, go by different names depending on their application area, for example: * Food: Recipes, * Chemicals: Equations, * Building: Plans. For this chapter you should start with a fresh database that includes demo data, with :mod:`mrp` (``Manufacturing``) and its dependencies installed and a generic chart of accounts configured. As you will notice, when you select ``Manufacturing`` to be installed, OpenERP will install the linked applications automatically. .. raw:: html
