Currently North America is facing significant challenges as a result of the deteriorated infrastructure assets and the limited repair funds. A recent study showed that Canada's roads and highway infrastructure networks need $66 Billion over the next 10 years to bring these networks to acceptable service conditions. Among the transportation assets,...

Context 1
... basic BDMS has been extended to incorporate work zone planning into the decision support system. To do that, the spreadsheet system was modified to incorporate the user cost calculations as a function of the repair decisions (in Figure 4) and the work zone decision variables discussed earlier. Also, an optimization module was incorporated to select the optimum work zone strategy for each bridge during its repair time. ...
Context 2
... chromosome structure is made of string of 4 elements (genes), each representing the number of days associated with one of the four work zone strategies, as shown in Figure 4. To evaluate a possible solution (chromosome), the objective function is to minimize the sum of user cost for each bridge along its planning horizon (Equation 2). ...
