Operational efficiency of tow trucks: a case based evidence from an Indian automobile manufacturer

Abstract

Purpose The purpose of this paper is to examine and model the in-plant operational efficiency of tow trucks of an automobile manufacturing plant. Even though, tow trucks contribute toward the improvement of operational performance, little case-based evidence prevail in the literature. For this purpose, a case study has been conducted in an Indian automobile manufacturer to address the prevailing issues in material handling (MH). Design/methodology/approach Initially, this paper focuses on grouping of the sequence parts and finding the shortest path among the groups. To elucidate this, an analytical framework based on the distance and stuffing quantity is proposed. A fuzzy Dijkstra’s algorithm is used to solve the issues in grouping of the sequence parts and shortest path among the groups. Findings This study addressed the four aspects of MH: move cost, time, distance and material by integrating the function of grouping, finding the shortest path and communication with low cost devices. The result shows that logistics routes and activities should not be interrupted by any of the external factors. The availability of stock is a key performance variable to attain efficiency. In addition to this, effective communication between the truck operators and the production line managers is key performance indicator. Originality/value The paper helps the automobile practitioners on increasing the efficiency of tow truck by systemizing the routes. Logistics routes and activities should not be interrupted by any of the external factors. The availability of stock is a key performance variable to attain efficiency. In addition to this, effective communication between the truck operators and the line managers is key performance indicator.

AS/R system travel time in class-based storage with different input-output point levels: a proposed formula

“…Sari et al (2007) demonstrate that AS/RSs can reduce inventory level and respond to customers’ needs in a timely manner, as well as improve space utilization and equipment. This has also positive impacts on enhancing material flows and on properly supporting production processes (Rose et al , 2021). AS/RSs are composed of storage racks, input/output (I/O) stations and storage/retrieval (S/R) machines, namely, automated stacker cranes, to handle unit loads without human intervention under the supervision of a computerized control system.…”
