The internal transport process (ITP) is carried out in logistics facilities such as distribution warehouses or transshipment terminals. This process determines the operating costs of such facilities and the costs of logistics services. One of the most important organizational tools for this process is scheduling. The ITP schedule can be evaluated based on criteria describing the workload of internal transport equipment. The article proposes indicators for the workload of employees and internal transport equipment. The task is supported by an appropriate calculation example.1. INTRODUCTION
Logistics facilities, such as distribution and production warehouses, consolidation points, cross-docking facilities, etc., are key elements of supply chains.
They perform the consolidation and deconsolidation of material flows, as well as their redirection to appropriate destinations and storage [6], [8]. These are the basic functions of logistics facilities, the fulfillment of which is the result of the implementation of the internal transport process (ITP) within them [2]. Effective implementation of ITP is crucial for operating costs and will translate into the prices of logistics services [6].
The internal transport process is defined as a set of tasks related to moving and/or changing the physical form of material units using appropriate equipment and personnel, organized and controlled by specialized information tools. ITP is an integral component of the logistics process carried out within a logistics facility. The logistics process includes moving, buffering, storing, and changing the physical form of materials. ITP only covers the transport of materials between functional areas of the facility and within them, as well as the buffering of these flows. Elements of long-term and short-term storage are not considered in the case of ITP [1].
2. INTERNAL TRANSPORT PROCESS SCHEDULE
Organizing ITP through scheduling is a way to improve its efficiency, i.e., increasing productivity while reducing implementation costs.
It is therefore justified to develop methods for constructing rational schedules, and thus improve the quality of technological designs for distribution warehouses and streamline management methods. One of the criteria for evaluating ITP schedules can be the degree of equipment and human workload. (…)
