Abstract: Abstract: Integrated innovation of wholesale market engineering technology in production base was able to effectively solve a series of problems of wholesale market in production base, such as a lack of circulation function, low level of technology and management. Meanwhile the integrated innovation of wholesale market engineering technology in the production base was also able to improve the level of wholesale market modernization. In order to carry out the engineering technology integration of the wholesale market in production base, integrative mentality and procedure of wholesale market engineering technology in production base were put forward, with the aim of engineering construction. The integrative process of the engineering technology of wholesale market in production base was made up of the following 3 steps: Technology classification, technology evaluation, and integrative scheme construction. Based on the realization integrity function of wholesale market, classification method of engineering technology was proposed with wholesale market itself as the main subject. The evaluation index system was established for the purpose of engineering construction. The weights of these indexes were reckoned by use of a comparison matrix of analytic hierarchy process built in the software of MATLAB 7.6. Grade criteria for the integration technology evaluation were built by combined method of qualitative analysis and quantitative calculation. Ice storage function module of small wholesale market in production base in Hainan province was taken as a case. Based on the established process and method, the framework for classification of engineering technology of ice storage function module for small wholesale market in Hainan production base was set up with 5 grades and 8 facilities and equipment. The evaluation index system for engineering technology integration of ice storage function module of the small wholesale market in Hainan production base was made up with 3 grades and 15 indices. Finally, the feasible integration scheme of the engineering technology of storage function module for small wholesale market in Hainan production base was put forward with 3 levels and 12 integration schemes. The number of the high level integration scheme of engineering technology of storage function module for small wholesale market in Hainan production base was one. The numbers of the integration scheme in medium level and low level were 7 and 4, respectively. The high level of integration scheme of engineering technology of the storage function module for small wholesale market in Hainan production base was made up of fabricated store house, ultrasonic humidifier or high-pressure atomizer, and ammonia refrigeration equipment. The evaluation result of this integrated engineering technology was 3.953. All these results would provide theoretical basis for engineering technology integrative of a small wholesale market in Hainan production base.
