Reasonable arrangement of production scheduling of prefabricated components can reduce the production cost of prefabricated buildings.Under the precondition of considering the constraint of component production resources,theproduction scheduling optimization model of prefabricated components is established.Then,an improved discrete Grey Wolf optimization algorithm,IGWO,is designed to solve the model.Finally,it is tested in a real case,and the improved discrete gray Wolf algorithm,heuristic algorithm Palmer method and genetic algorithm are compared.The results show that the improved discrete Grey Wolf algorithm is superior to Palmer method and genetic algorithm,and can improve the production efficiency of prefabricated components after reasonable scheduling.
To better realize the control of safety risks in the construction of prefabricated buildings (PB), scientific measures were taken to rationally allocate the resources of the construction site. Firstly, the safety risk factors of PB construction were identified by the WBS-RBS method and a fuzzy Bayesian network was set up to quantify the probability of risk. Then the construction network plan was utilized to achieve the transmission between risks. Finally, the control model with the minimum safety risk loss as the objective function was established, and an improved bat algorithm (IBA) adding an inertia weight that obeys exponential decline was proposed to solve the model. The results show that IBA has better astringency and optimization accuracy, and can better find the optimal solution for the safety risk control model of PB construction, so as to achieve the optimization of safety risk.

Urban waterlogging risk simulation and early warning is an important basis for guiding urban disaster reduction.Based on the review of relevant research at home and abroad, it is found that the technical model in urban waterlogging risk simulation needs to be transformed from two-dimensional plane model to three-dimensional space model, and the research focus needs to be transformed from rainstorm forecast and disaster loss assessment to waterlogging risk early warning.In the future development trend, it is necessary to establish a research system of “multi-source data-precision analysis-dynamic warning”.Further, according to the regional characteristics of the study area, various influencing factors are extracted and superimposed, and multi-source data of urban geography, hydrology, meteorology, transportation, planning and other disciplines are integrated for coupling analysis.In the multi-scale system, the spatial three-dimensional model is used to simulate the multi-scenario waterlogging risk, realize the dynamic early warning of waterlogging risk, and provide new ideas for the development of resilient cities.
In recent years, high-speed railway stations have become urban transportation hubs and important driving forces for economic development.However, in China, the spatial development of stations and surrounding areas is subordinate to different departments, and railway departments are separated from local governments, so the integration degree of stations and cities is not high.Road network is the skeleton of a city and the basis for the good development of a city and a region.Taking six high-speed railway stations in China and Japan as the research object, this paper uses space syntax and GIS software to compare and analyze different road network structures.It is found that there are great differences between China′s low-density large road network and Japan′s high-density small road network in terms of road network density, accessibility, convenience and spatial perception.The spatial perception ability of different road network structures is in order of hybrid, square format and freestyle, and Tokyo station has the best spatial perception of hybrid road network.By comparing and analyzing the differences of network structure of high-speed railway stations between China and Japan, this paper aims to provide reference for network planning of new high-speed railway stations and network optimization of existing high-speed railway stations in China.

O′Neill, a great playwright in American drama of Postmodernism, devoted all his life to the exploration of man′s spiritual identity and composed a paean to man′s confrontation with fate.In his masterpiece The Hairy Ape,he represents a microcosm of modern human society with the protagonist Yuncker′s failure in seeking a harmony among nature, society and spirit, and reveals an ecological tragedy of the industrial society.From aspects of social ecology, spiritual ecology and natural ecology, this paper analyzes the disadvantages of Industrial Civilization in the period of the rapid development of capitalism exposed by the play: the loss of morality, the deterioration of nature and the alienation of human nature, and presenting O′Neill′s forward-looking ecological consciousness and compassionate ecological care which can not only enrich interpretation of this classic drama but also of a great practical significance of awakening people to reflect on the dual crisis of ecology and civilization in today′s world.

On the basis of literature review, the evaluation model of coupling coordination degree of advanced manufacturing industry and modern service industry was constructed.According to the statistical data from 2011 to 2020,the contribution value, coupling coordination degree and changes of the two industries in Liaoning Province in the past ten years were evaluated.The research found that the average coordination degree of Liaoning Province in the past ten years was 0.5837,which was at a barely coordinated level.Since 2013,its coupling development process has shown a U-shaped change, and it began to recover after reaching the lowest point in 2018.Finally, on the basis of empirical research, it is proposed that we should focus on tackling the “choke” technology to build an advanced manufacturing industry cluster; strengthen the opening up, focus on cultivating and introducing modern service industries; promote the collaborative innovation of the two industries and create a complete industrial chain.
Taking Liaoning Province as an example, this paper studies the construction and method of its equipment manufacturing enterprises′ scientific and technological innovation capability index system, and constructs a measurement index system of equipment manufacturing enterprises′ scientific and technological innovation capability combining the analytic hierarchy process（AHP）and information entropy.In this study, firstly, we need to establish an evaluation index system, secondly, we need to build a hierarchical model, construct a judgment matrix, and then calculate the weight vector and consistency test of hierarchical single ranking.Finally, we need to use information entropy to modify the weight obtained by AHP.Based on the evaluation results, the paper puts forward some countermeasures and suggestions, such as strengthening the construction of enterprises′ independent innovation capacity, establishing a horizontal relationship layer, establishing a strategic alliance between industry, education and research, improving the industrial concentration of equipment manufacturing industry, and reshaping the boundary between the market and the government.
