Elements of methodology of analysis and synthesis of operations and procedures for maintaining vessel safe operation in companies

The analysis of the model of the “ship - human element - environment” system based on the associative-structural approach is carried out and its operation in a stationary mode is shown, providing the required level of navigation safety with a constant logical operator of communication between system-forming factors. Minimizing dangerous phase transitions in the “ship - human element - environment” system has been proved possible by purposefully using the allocated resource and conducting multiparametric control of operations with a minimum of information necessary for equipment diagnostics and instructing the ship’s crew. The research results of developing the scenarios of ship operations and procedures of managing the condition of the vessel, creating the elements of the theory of the vessel safe operation in non-standard and emergency situations in conditions of phase transitions of the states of the structure-forming factors of the system are presented. Elements of the methodology for analyzing and synthesizing scenarios of operations and procedures for managing the state of safe operation of the vessel in steady-state mode within the framework of a program-target approach in the form of logical programs have been developed. The description of the algorithm for updating scenarios of operations and procedures for managing the state of safety of the vessel in special conditions of navigation and in emergency situations is given. The developed directions for improving the control over safe operation of ships by means of multi-criteria optimization of the production and navigation process and by drawing up scenarios and management procedures help reduce the accidents on ships in the transport, oil and gas and fishing industries of the Russian Federation.
