The invention discloses an emergency material allocation optimization method in an extremely cold working environment. The method comprises the following steps of: analyzing an engineering construction environment in an extremely cold region; analyzing path selection preference of a decision maker, selecting transportation time, transportation capacity and road section risk degree as three reference points, designing a path decision cumulative foreground value function of multiple reference points, and constructing a transportation path selection model; making an emergency material supply scheme at the initial moment, and selecting psychological expectation of the decision maker as a dynamic reference point; after supplying for a period of time according to the initial scheme, judging whether the actual loss exceeds a reference point or not, and if the actual loss exceeds the reference point, constructing a dynamic material adjustment model and adjusting the initial supply scheme; formulating a satisfaction criterion of emergency material supply from the perspective of affected public; and converting an emergency material allocation multi-objective model into a single-objective model by using three methods. Technical guidance is provided for emergency guarantee of large engineering construction in the complex environment of an extremely cold region.
Description
technical field [0001] The invention relates to the guarantee of supply of emergency materials in the high-cold working environment, and specifically develops an optimization method for emergency material deployment in the high-cold working environment. Background technique [0002] The alpine working environment faces harsh climate, complex geology and other conditions, which brings great challenges to the engineering construction in this area. The materials needed in engineering construction include the necessary materials for personnel's life, as well as steel, cement, oil, mineral powder, fly ash, admixtures and other engineering construction materials in large demand, high quality requirements, and various categories. Due to limited traffic conditions, scarce construction land, and weak construction of supporting support facilities in such areas, it is difficult to store and transport materials, and it is extremely difficult to guarantee the supply of materials in case ...
