Embodiment Construction

[0044] The present invention will be further described below in conjunction with accompanying drawing.

[0045] Concrete steps of the present invention are:

[0046] Step 1 needs to obtain data such as the number of beer saccharification equipment and fermentation tanks, beer varieties, length of scheduling time period, fermentation cycle, etc. These data can be obtained through beer manufacturers or statistics during the production process.

[0047] Step 2 establishes the comprehensive production scheduling estimation model through the production process parameters.

[0048] ①Material balance constraints

[0049] In each time interval t, according to the material balance, the storage amount in the fermenter should be the feeding amount of the saccharification equipment to the tank. It can be described as follows:

[0050] P u 2 , t = P ...

Abstract

The invention relates to a production scheduling optimization method for a beer saccharification process, wherein beer enterprises are not ideal in scheduling effect because of formulating production scheduling schemes by virtue of artificial experience presently. The production scheduling optimization method disclosed by the invention comprises the following steps of: establishing a production scheduling mathematical model on the basis of a technological process mechanism and first, and then converting to a discrete form capable of solving by virtue of an ant colony optimization algorithm, and finally determining a production scheduling method for the beer saccharification process. The invention discloses a saccharification production scheduling method with a high global optimization capacity aiming at some problems in optimized scheduling for beer saccharification production, and the optimization method has the characteristics of openness, robustness, parallelism, global convergence, and no special requirements on problematic mathematical forms, and the like.

Description

technical field [0001] The invention belongs to the field of information and control technology, relates to automation technology, in particular to a production scheduling optimization method for a beer saccharification process. Background technique [0002] Beer saccharification production is an intermittent production process with complex system and long production cycle. The production includes various processes, and the processes are interrelated. At present, the market competition among beer companies is becoming increasingly fierce, and reasonable production scheduling plays an extremely important role in improving the efficiency, market response speed and comprehensive competitiveness of beer companies. In particular, the continuous promotion of lean production methods in beer companies has forced the research on beer saccharification production scheduling to become more and more urgent. The beer production process has the characteristics of semi-continuous productio...
