Abstract: With the requirement to continuously improve detailed management in petro-chemical industry, the traditional single-alone planning optimization software gradually failed to meet the need. Using new information technology whose core is internet technology, a new generation of planning model system is developed in this paper, which is graphic and online, stressing on process orientation and collaborative application. By means of the basic model management, online model sharing and sending, and data dictionary management, the collaborative application is realized. By using graph modeling, data input through windows form, diverse result output, and error diagnosing throughout the process of modeling, the system becomes visual and user-friendly. Depending on the function of ‘input once and calculate many times', the sensitivity analysis can be easily made by users. The system security is guaranteed through authorization management. The real application results show that the model established using the system is reliable, and it can well support the planning optimization of the enterprises.
