Abstract
The model of the event log of the information system has been improved. The model contains the sequences of events consistent with implemented sequences of management actions within both the process approach and functional management approach. A strict linear order in time was assigned for each pair of events belonging to the same process. The model is designed to describe the prototype of the as-is business process. A case-based model of a business process, describing the features of its known implementations, reflected in the event log, has been proposed. The model combines a set of implemented sequences of operations of each process and takes into consideration the time to implement these operations, as well as the resources they need. When describing the time to implement the operations of a process, delays in accessing the company’s shared resources are taken into consideration. The model makes it possible to predict the terms of completing the set of business processes competing for the resources when removing or adding new processes to this set. The technology for changing the sequence of access to resources for a set of business processes competing for these resources within the process management was developed. The proposed technology uses the case-based model of a business process to calculate the order of access to resources. The technology provides an opportunity to calculate the total reduction in delays over the implementation time in relation to the implementation terms when processes are competing for resources. The technology makes it possible to choose how to access resources with the least delay in relation to operations completion deadlines for the known variants of a business process implementation. This enables a DM to assess the possibility of launching new processes that use shared resources by reducing the waiting time when accessing these resources
Highlights
The process approach to management is based on the description of a company as a system of inputs, outputs and business processes that transform input resources into products or services at the output
Existing methods of process mining make it possible to construct the models of separate business processes taking into consideration the time of operations execution recorded in the log [13]
The model of the event log of the information system was improved by introducing orderliness for pairs of events of one process in a single sequence of events that recorded a parallel solution of several problems
Summary
The process approach to management is based on the description of a company as a system of inputs, outputs and business processes that transform input resources into products or services at the output. The problem of competition for resources is relevant for end-to-end business processes [5] The latter provide products and services to external consumers. Timely adjustment of the models of the end-to-end business process in order to change the sequence of access to resources is a relevant task. The solution of this task creates conditions for the timely implementation of a set of end-toend business processes within the time limits suitable for a consumer. That is why the problem of adjusting the process models by changing the sequence of access to the shared resources of a company during the implementation of business processes requires its solution
