“…Acta Scientiarum. Technology, v. 43, e51796, 2021 Also, we can see that the results are consistent with the existing literature, since Ozkok and Cebi (2014) in their work, which aimed to make a general analysis of all types of launching methods from of a SWOT analysis, multicriteria decision methods (MCDM) and fuzzy logic, concluded that dry dock and airbag options are considered the most appropriate launching methods in terms of cost, performance and risk factors. The authors further state that the airbag method is emerging in far east shipyards and it is believed that those who prefer the use of dry dock or airbag launching will benefit from a substantial gain related to competitive power.…”

Ship repair has gained prominence as a service offered at the shipyards following a crisis in the shipbuilding industry, which has seen a fall in demand for new constructions, causing many companies in the sector to stall, especially shipyards. For a repair yard to be economically viable, in times of crisis, cost reduction is essential to make a sustainable business, so this comparative study aims to check the technical and economic feasibility of this change in the type of dry-docking. The present work deals with a comparative study between the use of the longitudinal slipway and the airbags for dry-docking and repair of river barges. The study sought to identify data from the vessels used for this project, to verify the average displacement of these vessels to analyze the airbags' carrying capacity, as well as the size of the winch to perform the dry-docking service. Since most repair yards use leased areas, the flexibility achieved with the use of airbags, as well as the reduced need for investments in the area, are benefits provided by using them. This work presented satisfactory results for the use of river barge docking airbags as a competitive alternative in repair services.

Purpose The purpose of this paper is to implement the strategies selection process in a proposed formulated mathematical framework to prioritize selected strategies with the interaction of other groups of strategies, known as the strategies interaction model (SIM). Design/methodology/approach SWOT analysis is a popular useful strategic planning tool, which analyzes organizations internal and external factors. The traditional SWOT procedure lists internal and external factors and derives four groups of strategies based on the organization’s strategic position. SWOT is easy to use as a business analyzing tool, while it is not competent enough for strategic formulation. With the emergence of the economy’s vicissitudes, undulations in the markets and multiple changes, and various variables in the industrial competitive environment, selection of the organization strategies confront uncertainty in decision making. The SIM framework presents a solution to select alternative strategies for organizations in unpredictable situations. Findings The findings show that SIM is a reliable approach to evaluate, select and rank organization’ strategies. SIM proposes alternative strategies due to the uncertainty of the organization’ environment with respect to the four strategic positions. The SIM’ proposed ranking process is in accordance with the highest impact of each strategy on each other. Furthermore, it possesses advantages of AHP, ANP and other applied multiple criteria decision-making (MCDM) techniques in SWOT analysis. Practical implications In this paper SIM is applied within a dairy company located in the north of Iran. Originality/value SIM has the advantages of the classic SWOT and fills the gaps of MCDM methods application in the SWOT analysis. Moreover, it provides a formulated algorithm for the organizations to face the uncertainty of the environment. SIM philosophy can be widely used in the decision and managerial implications.

In the past, although many researchers used analytic hierarchy process to various fields, few applied analytic hierarchy process to solve the military problems. In this article, an application of analytic hierarchy process to choose the optimal transportation mode in the military logistics is explored. The results show that the transportation by the Army's warships takes priority because the self-reliant transportation provides offshore islands a good shipping service in a short transit time, on a reliable schedule and by the professional armed forces. In respect of the measuring dimensions, related literature, expert groups and offshore island military units give priority to the timing because the timing is the key to either the civilian commercial economy or the military transportation. Moreover, this article also finds that related literature, experts and basic-level military units have different perspectives on the evaluative criteria owing to their different views of economy (strategic planning), resources (military budget), hierarchies (managers, planners and demanders) and port facilities (military investments). Finally, this article also analyzed and compared the commercial logistics and the military logistics and then summarized some major differences between the commercial logistics and the military logistics. It not only provides an important basis for future academic studies on the logistics but also provides a useful reference for the logistics practices.
