MULTIPLE PROJECT SCHEDULING OF PRECONSTRUCTION ENGINEERING ACTIVITIES, AND DISCUSSION

SYSTEMATIC METHODS FOR SCHEDULING THE PRECONSTRUCTION ENGINEERING AND RIGHT-OF-WAY ACTIVITIES OF THE VARIOUS STATE HIGHWAY PROGRAMS ARE REVEALED IN SEVERAL APPROACHES. IN EACH APPROACH THE SCHEDULES ARE ARRIVED AT BY ALLOCATING THE ASSUMED FIXED POOL OF CLASSIFIED MANPOWER RESOURCES TO A PRIORITY ARRAY OF PROGRAMED PROJECTS. THE BANALCE-PERIOD APPROACH IS A THEORETICAL PROCEDURE WHICH OUTLINES A SET OF RULES THAT IS APPLIED IN AN ITERATIVE MANNER FOR THE ENTIRE HIGHWAY PROGRAM PERIOD. EACH REPEAT OF THE PROCEDURES IS FOR A PREDETERMINED TIME INTERVAL OR BALANCE PERIOD. DURING THE BALANCE PERIOD THE ENTIRE POOL OF FIXED MANNER RESOURCES IS APPLIED TO THE PRIORITY ARRAY OF PROJECTS. NETWORK DIAGRAMS OF EACH PROJECT AND CRITICAL PATH METHODS ARE UTILIZED TO ALLOCATE THE RESOURCES AND THUS CREATE A SCHEDULE OF PRECONSTRUCTION ACTIVITIES. THE APPLICATION OF THE BALANCE-PERIOD METHOD, ALONG WITH SEVERAL CORRELATING RULES FOR ACTIVITY CONTINUITY, PRODUCES A SCHEDULE THAT IS BASED ON PROJECT PRIORITY AND THE AVAILABILITY OF MANPOWER RESOURCES. FURTHERMORE, THE BALANCE -PERIOD METHOD IS MECHANICAL AND THUS SUITABLE TO BE WRITTEN AS A COMPUTER PROGRAM. THE SIMILARITIES AND DIFFERENCES BETWEEN RAMPS AND RPSM WERE EXPLORED BY TESTING SAMPLE PROBLEMS WITH EACH PROGRAM. THE PRACTICAL ASPECTS OF USING EITHER THE THEORETICAL BALANCE-PERIOD APPROACH, THE RAMPS PROGRAM, OR THE RPSM PROGRAM ARE PRESENTED. HIGHWAY DEPARTMENT POLICIES AND OPERATING METHODS HAVE SUBSTANTIAL EFFECTS ON THE FEASIBILITY OF THESE APPROACHES. NUMEROUS TECHNICAL PROBLEMS MUST BE SOLVED TO ACHIEVE FULLY OBJECTIVES OF HIGHWAY PROGRAM ADMINISTRATORS. /AUTHOR/
