(c) A tourist in New York City wants to visit 8 tourist sites using local transportation. The tour starts and ends at a centrally located hotel. The tourist wants to spend the least money on transportation.

(d) A manager has m employees working on n projects. An employee may work on more than one project, which results in overlap of the assignments. Currently, the manager * Problems 459 meets with each employee individually once a week. To reduce the total meeting time for all employees, the manager wants to hold group meetings involving shared projects.

(e) Meals-on-Wheels is a charity service that prepares meals in its central kitchen for delivery to people who qualify for the service. Ideally, all meals should be delivered within 20 minutes from the time they leave the kitchen. This means that the return time from the last location to the kitchen is not a factor in determining the sequence of deliveries.

(f) DNA sequencing. In genetic engineering, a collection of DNA strings, each of a specified length, is concatenated to form one universal string. The genes of individual DNA strings may overlap. The amount of overlaps between two successive strings is measurable in length units. The length of the universal string is the sum of the lengths of the individual strings less the overlaps. The goal is to concatenate the individual strings in a manner that minimizes the length of the universal string

11-3 Propose a tour using the Excel TSP Tool provided. Provide a business justification for the route/routes selected.

Seers Service Center schedules its daily repair visits to customers. The matrix ‘Tij‘ below gives the travel time (in minutes) between the service center (row 1 and column 1) and seven jobs. The jobs are assigned to one of the repairpersons during an 8-hr shift. At the end of the day, the repairperson returns to the service center to complete paperwork

(a) Compare the lower bounds on the optimum tour length using both the assignment model and linear programming. Is the assignment model solution optimum for the TSP?

(b) Given that journeying between jobs is nonproductive and assuming a 1-hr lunch break, determine the maximum productivity of the repairperson during the day

11-2.1  Attempt to improve the AMPL Code provided to provide a closed tour. In addition to submitting the final code you came to provide discussion about concerns and approaches used.

A book salesperson who lives in Basin must call once a month on four customers located in Wald, Bon, Mena, and Kiln before returning home to Basin. The following table gives the distances in miles among the different cities.

Miles between cities

Basin Wald Bon Mena Kiln

Basin 0 125 225 155 215

Wald 125 0 85 115 135

Bon 225 85 0 165 190

Mena 155 115 165 0 195

Kiln 215 135 190 195 0


The objective is to minimize the total distance traveled by the salesperson.

  • Write down the LP for computing a lower-bound estimate on the optimum tour length.
