Tables 1 and 2 contain the data from the first part of the project. Table 1 presents the amount of vaccine demand for each demand point, and Table 2 presents the distance between each potential health center and the demand point. Table 1.

This time, the trucks can carry the demand of multiple demand points in a single trip. The first alternative of the logistics department is the trucks they considered in the initial planning phase (Truck Type 1). They are also considering an alternative truck (Truck Type 2) that can be used for distribution. The properties of both truck types are given in Table 4. In each health center, one truck type should be used for managerial reasons, but different health centers can use different trucks; i.e., health center A may use three trucks of type 1, while health center B uses two trucks of type 2.

The distances between the demand points allocated to the same health center are given in Tables 5-7. Determine the routes of the trucks to be used in each health center. Table 5.
