Routing and scheduling of wardens for public car park inspection

Abstract This paper presents a case study on the inspection operations of public car parks which employ a “coupon parking” system with checking by wardens. The problem is to determine an optimal staffing level for the wardens as well as an optimal schedule for their deployment. A framework is laid out in the paper for modeling the car park inspection policy, and some heuristic procedures are developed for the determination of number of wardens required in a zone. The proposed model has been tested against some field data, leading to results that provide a more rational and systematic basis for the scheduling of inspection operations.
