SUSTAINABILITY NAVAL BASE WITH THREE MAIN ASPECTS AS ONE OF THE INDONESIAN MARITIME DEFENSE AND SECURITY ELEMENTS WITH SYSTEM DYNAMIC APPROACH

The development of Naval Base requires very strategic planning and calculation to obtain the sustainability of the base. This is intended so that in the future the existence of these bases can continue and exist, which is not disturbed by changes and System Dynamics from various aspects that develop and change over time. Sustainability of Naval Base is determined by many factors that are interrelated with one another as a very complex system arrangement so that a comprehensive analysis of various related aspects of the researcher is compiled into Three main aspects namely Defense Security Political Aspects, Economic Aspects and physical aspects of naval base. In this paper, the researcher will compile a model with System Dynamics approach to the sustainability of the Naval Base that is the object. Then also use Fuzzy Weighting from the elements of subjectivity which will be projected to become elements of objectivity, which also involves data / variables that are qualitative and quantitative. This has never been discussed in previous site selection studies. The complexity of the variables and the dependency relationships between variables in the system, and the decision makers' subjectivity can be identified and smoothed with the Fuzzy Weighting to get the weighting value so that the integration between the System Dynamics model with the Fuzzy Weighting method gets the analysis results of the Naval Base sustainability system based on three main aspects namely Defense Security Political Aspects, Economic Aspects and Physical Aspects of Naval Base. The results of the assessment of Fuzzy Weighting put the Defense Security Political Aspects in the first place with the value of the weight of the influence of interest 3.60, followed by the second position of the Physical Aspects of Naval Base with the value of the weight of the influence of the interest 3.40 and in the third position the Economic Aspects with a value of 3.0. Then the results are integrated into the System Dynamic calculation that produces sustainability values from three main aspects including Defense Security Political Aspects with strategic value of base area 36.42, then from Economic Aspects with land availability value 3.94, and Physical Aspects of Naval Base with physical capability values base 21.07.

Complex Project

This study analysed a system dynamics model for outsourcing engineering services in a large and complex project organisational structure that is typically associated with design-build (DB) project delivery. A literature review indicated that most of the reviewed papers implied the project engineering resources were totally insourced or the authors were silent regarding any resources that were outsourced. Comprehensive sensitivity analysis of various model variables was performed, which indicates that the quality and productivity of the outsourced resources as well as the initial number of assigned experienced engineers significantly impacted the amount and timing of engineering work completion. Project outcomes were also impacted by varying the number of initial and changed engineering tasks. The decision to insource/outsource engineering work on DB projects may have significant cost and time impacts, which should be considered by decision makers.

Sd Model

Thank to developed SD model, decision makers can create appropriate policy. The importance of passenger numbers in compartments increased due to COVID-19, and managers didn't want to increase passengers in compartments too much. In this study, a model will be developed in Vensim package program. The model will be developed for analyzing passenger flows. Different scenarios can be tested thanks to developed system dynamics model. Subway passenger flow was analyzed via system dynamics. The SD model was developed in Vensim PLE package program. Passenger flow was defined as rate, and stations are defined as stock. Managers would change timing according to time, and effects of these changes can be observed via the model.

Water Catchment

This paper analyzes, evaluates and simulates a water catchment and consumption process using a system dynamics model to support water resources management. After creating a theoretical model, real data from São Carlos in Brazil were used. The water availability situation was assessed using the catchment data analysis of the main surface and groundwater sources and the supply data, subdivided into four categories of use. Simulations were carried out by evaluating historical data and further simulations of future scenarios. The average annual consumption was 15.8 million m3. The volume of water catchment in 2017 was more than 35 million m³, and from this total 43.5% of treated water was wasted due to losses. Domestic consumption accounts for more than 80% of the total and greywater reuse can reduce this impact, which means economizing approximately 9 million m3/year. Modeling allows decision makers to analyze the evolution of parameters and the scenario projection.

Selection Of

System dynamics models can produce knowledge for decision-makers and, consequently, provide better choices. To be effective in its purpose, a model must reproduce an observed problem situation effectively. Hence, the compatibility between the observed problem situation and the created model is essential and represents a considerable challenge. In this context, this paper aims to describe an adaptation of the problem structuring method ‘Strategic Options Development and Analysis’ (SODA), used in the Problem Articulation (Boundary Selection) step of the system dynamics modelling process. In summary, this adaptation consists of: (1) Selecting of stakeholders; (2) Capturing, aggregating and interpreting the insights using cognitive and causal maps, and (3) Using the interpretation of the causal maps for building a system dynamics model. The method proved to be satisfactory since it was able to direct the construction of a System Dynamics model based on a problem situation perceived by stakeholders acting in the native forests of the state of Santa Catarina, Brazil.
