Design And Implementation Of Catering Crowdsourcing Platform Based On Decision Analysis Model

The rapid development of Internet technology and mobile applications has brought great changes to people's lifestyle.This paper starts from the user's point of view,takes the user's experience and demand as the core,in order to simplify the interactive process of online ordering,provide diversified and customized ordering services for users,and proposes a online ordering crowdsourcing solution on the basis of traditional online ordering.The main work of this paper is to model the domain of the catering crowdsourcing platform,and to realize and verify the automated order allocation framework.In the process of implementing the system,in order to solve the core difficulty of how to select the best supplier to automate the allocation of crowdsourced orders,this paper proposes an effective catering crowdsourced order allocation framework based on DEMALTEL mehtod and Taguchi loss function.By using DEMALTEL method,the framework for the analysis domain experts for the food supply in the system of 13 kinds of evaluation standard,has carried on the analysis and calculation,it is concluded that the weights of evaluation criteria,according to the classification of the various evaluation standards using Taguchi loss function to catering supplier to calculate the comprehensive score,to choose in order to choose the optimal supplier for processing.In this paper,the analysis and design of the framework are discussed in detail,and the validity of the framework is verified by using the actual data.In response to rapid changes in technology and demand the Internet environment,ensure that the system can quickly response to the change of demand,has high scalability,are studied in this paper,the domain driven design mode,and it in the actual project development practice,thus in the process of system analysis and design to ensure the demand of full coverage and system architecture of reasonable construction,put forward a set of system development scheme based on domain driven design patterns.Through systematic analysis,design and coding implementation,this paper has completely verified the development scheme based on domain-driven design,realized the catering crowdsourcing process,and designed and implemented the automatic order allocation algorithm to solve the core difficulties of catering crowd-sourcing order allocation,and verified the feasibility of catering crowd-sourcing.
