Multi-level inventory control method and system for engineering materials

Abstract

The invention discloses a multi-level inventory control method for engineering materials. The method comprises the following steps: a multi-level inventory plan for engineering materials in a plan period is provided, a two-stage supply chain structure is adopted in the multi-stage inventory plan. The two-stage supply chain structure is composed of suppliers and a construction site. One kind of materials of one construction site is supplied by one supplier, one supplier can be responsible for supplying one kind of materials of multiple construction sites, and the multi-level inventory plan under the two-level supply chain structure can output two levels of plans, namely a construction site-oriented allocation plan and a supplier-oriented production plan. According to the method, under theengineering material supply chain environment, the mutual influence of inventory between different levels of nodes is considered, the multi-level inventory planning method is designed, global optimization and control over the supply chain inventory are achieved, and the engineering material supply chain multi-level inventory plan is more effective in actual operation.

Description

technical field [0001] The invention belongs to the technical field of engineering management, and in particular relates to a multi-level inventory control method and system for engineering materials. Background technique [0002] Inventories have historically been viewed as an important means of protection against risk and uncertainty. Traditional inventory management is mainly considered from the perspective of a single node, but this approach is obviously not enough from the perspective of the overall supply chain. In the supply chain environment, the inventories of nodes at different levels have mutual influence. To realize the global optimization and control of the supply chain inventory, multi-level inventory planning is especially necessary. [0003] The fundamental driving force for the operation of the engineering material supply chain lies in the pre-product demand plan formed by the project progress plan, which then drives the arrangement of the pre-product produ...

Problems solved by technology

[0004] At present, the inventory management of engineering materials is relatively casual and fragmented. The inventory management of engineering materials is often formulated based on the experience of managers and actual construction needs. In fact, the inventory management of engineering materials is very important to the project schedule and construction plan, especially for If the construction period is strictly required, if the matching of engineering materials is not in place, the construction period will be delayed and the overall cost of the project will be increased.
