Robust optimal design of agri-food supply chain network under demand uncertainty and raw material price uncertainty
摘要
Abstract
The competition between modern agri-businesses is not only the competition between production enterprises but also the competition between the agri-food supply chain networks (ASCN) including the core production enterprises.To improve the competitiveness of ASCN,the strategic decision of optimal design of ASCN is crucial.The optimal design of ASCN is effective to improve the operation efficiency of ASCN and reduce the operation cost and operation rise For traditional design of ASCN,all parameters including demand quantity and cost coefficients are assumed to be deterministic.Nevertheless,the uncertainties of supply,production and demand often exist in practice.Therefore,in this study we investigated the problem of robust optimal design of ASCN considering the uncertainties of supply and demand faced by ASCN.The aim is to develop a mathematical model for the robust optimal design of ASCN and is to present an effective optimization method to obtain robust solution for the addressed problem.In the first part,firstly the robust design problem of multi-echelon agri-food supply chain network (ASCN) with single non-perishable product is stated in detail.Then the parameters and variables of the optimization model are explained.Lastly,a mixed integer linear programming (MIP) model is presented for robust optimal design of ASCN,in order to minimize the sum of total cost of ASCN and the risk cost of uncertainty.The model integrates the decisions on facility location,capacity selection and transportation mode selection.In the model,the demand uncertainty and raw material price uncertainty are considered and are described by the scenario-based method.In the second part,a meta-heuristic named particle swarm optimization (PSO) is adopted to solve mid-to-large scale problems because the problem of robust design for ASCN belongs to the NP-hard problem.To avoid the stagnation of search of basic binary PSO (BBPSO),a newly proposed modified binary PSO (MBPSO) is utilized,which adopts the updating mechanism based on the concepts of the genotype-phenotype representation and the mutation operator.Moreover,an adaptive mutation operator is developed and embedded into the MBPSO.In the adaptive MBPSO (AMBPSO),the mutation probability is automatically increased if the global best particle keeps unchanged more than ten generations.For comparison purpose,the BBPSO with adaptive mutation operator (called ABBPSO) is also presented.The implementation procedure of the PSO approaches through LINGO and VC++ 6.0 is lastly described.In the third part,three cases of apple supply chain are constructed in order to test the effectiveness of the MIP model as well as MBPSO and AMBPSO.Using the three cases,the validity of the developed model is verified by analysis of case computation via LINGO.Then,the AMBPSO is compared with the existing BBPSO,MBPSO and ABBPSO against three cases.The comparison results show the effectiveness of the AMBPSO for robust design of ASCN.The computation results also indicate that the proposed AMBPSO is superior to existing BBPSO and MBPSO.In addition,the following conclusions are drawn through the comparison study:the MBPSO is better than the BBPSO with respect to exploration ability,and the adaptive mutation operator is helpful to improve the global optimization ability.In summary,the proposed MIP model for robust optimal design of ASCN problem is valid and the developed AMBPSO is effective and efficient to solve the problem of robust optimal design of ASCN.The comparative study shows that the updating mechanism of MBPSO based on genotype-phenotype representation and the adaptive mutation operator are able to improve BPSO's global optimization ability.关键词
