A mathematical model was built up to solve the problem of optimal operational control by analysing the factors on an interceptor sewer system and a Fortran program was produced for this model. This paper shows that the optimal control states can be determined by working out the optimal flow rates by means of Linear Programming (LP). The result is very sensitive to interception points and the concentration weight coefficients over time. The result further highlights some practical applications for the existing sewer systems or the sewer systems under design.

A knowledge representation has been proposed using the state space theory of Artificial Intelligence for Dynamic Programming Model, in which a model can be defined as a six tuple M=(I,G,O,T,D,S). A building block modeling method uses the modules of a six tuple to form a rule based solution model. Moreover, a rule based system has been designed and set up to solve the Dynamic Programming Model. This knowledge based representation can be easily used to express symbolical knowledge and dynamic characteristics for Dynamic Programming Model, and the inference based on the knowledge in the process of solving Dynamic Programming Model can also be conveniently realized in computer.

Purpose:This paper reviews an area of interdisciplinary collaboration in the design of healthcare facilities that attempts to optimize hospital space-planning using automated statistical techniques from the discipline of operations research(OR).This review articulates Facility Layout Problems(FLPs)as a general class of OR ***,the review highlights limitations of these techniques,which necessitate an ethical and participatory engagement with computerized processes of healthcare ***/methodology/approach:An in-depth critical review was carried out,which revealed a number of common themes,collectively theorized as metamodeling processes,or models of models,through which various FLP modelling techniques can be challenged and debated in terms of their architectural viability,and ethical ***:This review provides a methodological basis for the further evaluation of computational *** was found that most of the reviewed studies are functionally focused on flow efficiency and,in general,do not consider broader contextual,relational,social,or salutogenic design ***/value:This review is the first on the subject written from an architectural *** can be used by a broad range of readers as its critical review of past and present hospital layout modelling techniques discusses their capabilities and *** such,it also enables them to consider ethical values while critiquing the epistemology of computational processes hidden beneath algorithmic outputs.

This paper studies a kind of urban security risk assessment model based on multi-label learning, which is transformed into the solution of linear equations through a series of transformations, and then the solution of linear equations is transformed into an optimization problem. Finally, this paper uses some classical optimization algorithms to solve these optimization problems, the convergence of the algorithm is proved, and the advantages and disadvantages of several optimization methods are compared.
