Abstract: 

CONTRIBUTION IN TENDERS IS A STRATEGY FOR TAKING NEW PROJECTS FOR GENERAL CONTRACTORS (GC), BUT, IN THE BEGINNING OF THESE TENDERS, THERE ISN' T ANY SPECIFIC ESTIMATION OF THE PLANT. THIS PROBLEM SOLVES DURING FINALIZATION OF PROJECT DESIGN AND ENGINEERING. IN THIS REGARD, MAKE OPPORTUNITY FROM TENDERS IS A VERY SERIOUS RISK FOR GCS. FOR REDUCTION OF THIS RISK, IT IS NECESSARY TO DO BASIC DESIGNS IN SEPARATE PHASE BEFORE TENDERING AND CONSTRUCTION TENDERS DO IN SEPARATE PROCEDURE. IN THE OTHER HAND, IN MANY OF THESE CONTRACTION A SPECIFIC BOUND FOR EACH CATEGORY OF PROJECT ITEMS IS VERY NECESSARY TO MAXIMIZE PROFIT AND REDUCE LOSE OF DOING ANY PROJECTS. THUS, GCS USE BOUNDED VARIABLES FOR EDITING AND REVISING PROJECT SUB ITEMS. IN THIS PAPER, IT WAS TRIED TO CATEGORIZE ALL OF THE PROJECT ITEMS AND DEFINED BOUNDED VARIABLES FOR EACH OF THEM TO PROPOSE A COMPREHENSIVE MODEL FOR THE PROJECT. THIS MODEL WILL BE SOLVED AND ANALYZED BY ONE OF THE KNOWN LP SOFTWARE (LINDO). FINALLY, AS A CASE STUDY, THE PROPOSED MODEL WAS APPLIED TO REVISING DISPATCH CUM BILLING SCHEDULE IN TAVAZON COKE MAKING PROJECT OF ESCO AND ACCEPTABLE RESULTS WERE ACHIEVED.
