The impact of occupational accidents on operating costs and occupational health and safety costs on the number of occupational accidents - an application in the aviation sector.

This article examines the dual effects of occupational health and safety cost (OHSC) fluctuations due to the occupational accident number (OAN), and the impact of the OAN on operating period costs (OPCs). Initially, OHSCs, OANS and other operational data from the company were compiled to build a foundational infrastructure. Subsequently, econometric analysis using regression techniques was conducted to identify relationships between OHSCs and OANs, and between OHSCs and OPCs.

Pythagorean fuzzy VIKOR-based approach for safety risk assessment in mine industry.

Introduction: Underground mining is considered one of the most hazardous industries and is often associated with serious work-related fatalities; this paper addresses job-related hazards and associated risks.

Method: A risk assessment approach is proposed (Pythagorean fuzzy environment) and a case study is carried out in an underground copper and zinc mine.

Results: Results of the study demonstrate that hazards can be categorized into different risk levels via compromised solutions of the fuzzy approach.

An approach for economic analysis of intermodal transportation.

A different intermodal transportation model based on cost analysis considering technical, economical, and operational parameters is presented. The model consists of such intermodal modes as sea-road, sea-railway, road-railway, and multimode of sea-road-railway. A case study of cargo transportation has been carried out by using the suggested model.
