[0078] (First cooperation plan creation device 100)

[0079] In the first combination plan creating device 100, a combination plan for receiving and mixing a plurality of types of raw materials is created based on the transaction target amount of raw materials. The so-called transaction target volume refers to the transaction target volume (scheduled transaction volume) by mine (loading place) and product. Each mine is contracted for the amount of transaction for each item, for example, in one year. By dividing the transaction volume in the period by the number of ten days included in the corresponding period, the target transaction volume for each ten-day period can be obtained. In addition, in this specification, a ten day means a unit of a period that divides a month into three.

no. 2 approach

[0506] As a second embodiment, an example in which the second coordination plan creating device 300 is introduced will be described. The second combination plan creation device 300 creates a combination plan for purchasing and mixing a plurality of types of combination raw materials based on the ship allocation plan created by the ship allocation plan creation device 200 . In addition, the configuration and basic processing operations of the second coordination plan preparation device 300 are the same as those of the first coordination plan preparation device 100, and reference is also made here to Figure 2 to Figure 11 Be explained.

[0507] figure 2 It is a figure which shows the example of system structure including the 2nd coordination plan preparation apparatus 300. like figure 2 As shown, when creating a coordination plan, the second coordination plan preparation device 300 accepts the operator's settings or imports from the database 400 the data of the following c...

no. 3 approach

[0618] In the above-mentioned second embodiment, in the ship allocation plan preparation device 200, as the restriction (equation 24) on the inventory of each item, the safety stock amount is ensured (not less than) for each individual item. However, in actual operation, it is possible to flexibly respond by substituting varieties with similar characteristics (multiple varieties having common chemical properties within a predetermined range: varieties that can be used by mutual substitution). For example, when the inventories of raw materials A and B are 50,000 tons and 0 tons, respectively, and raw materials A is 0 tons and B is 20,000 tons in the use plan, the inventory will run out if only the B type is considered. However, when the characteristics of the raw materials A and B are such that they can be used in place of each other, 20,000 tons of A are used instead of 20,000 tons of raw material B. Thereby, it is possible to prevent the stock from running out.

Abstract

A system for making an allocation to ships which transport a plurality of brands of composition raw material from a plurality of loading places to a plurality of unloading places, and a composition plan for mixing the received composition raw materials at the unloading places, respectively, is provided with a first composition plan making section which makes a first composition plan based on the preset target quantity of transaction of the composition raw materials for each loading place and band, a ship allocation making section which makes an allocation to ships based on the first composition plan thus made, and a database section which stores the allocation to ship thus made.

Description

technical field [0001] The present invention relates to the preparation of a coordination plan for receiving and mixing multiple types of raw materials (hereinafter also referred to as raw materials) and a ship distribution plan for transporting multiple types of raw materials from multiple loading points to multiple unloading points And ship allocation plan making system, method and procedure. [0002] This application claims priority based on Patent Application No. 2008-298596 for which it applied in Japan on November 21, 2008, and uses the content here. Background technique [0003] In many industries including iron and steel, various raw materials with various characteristics purchased in accordance with contracted purchase target quantities are mixed, and steel and other products and semi-finished products are manufactured using the mixed raw materials. At this time, it is required to formulate a transportation plan (called a ship distribution plan in the case of a shi...
