“…It is a framework for seeing interrelationships rather than things, for seeing patterns of change rather than static "snapshots.

The Indonesian tourism sector has become one of government’s focus points because of its significant contribution to economic development on all levels, district/city, province, or national. As an Indonesian city, Bandung has a lot of tourism potential with its local cultural diversity. The purpose of this research is to develop a conceptual model design of tourism, especially in Bandung city as one of the cultural identity cities in West Java. A system thinking approach with qualitative analysis, known as the Soft System Methodology (SSM), is used in this research. Qualitative data collection techniques were carried out by a purposive sampling technique which was obtained from the results of in-depth interviews with stakeholders that included academics, representatives of the government, communities, and businesspeople in the tourism sector. The result of this research is a conceptual model design for Bandung city tourism as the identity of a cultural city, called as Sunda Culture Center (Sunda Centrum).

“…Linear programming (lp) has been used extensively throughout the years with its applications in economics, health, engineering, supply chain and many more [9]. The key concept of linear programming finds applications in almost all aspect of life such as; personal diet planning to maximize certain nutrient [10], minimization of transportation cost of goods from warehouse to retail customers [11]. Linear programming is branch of Operation Research that seeks to select the best method and deals with the application of scientific models in decision making.…”

Time, raw materials and labour are some of the nite resources in the world. Due to this, Linear Programming* (LP) is adopted by key decision-markers as an innovative tool to wisely consume these resources. This paper test the strength of linear programming models and presents an optimal solution to a diet problem on a multi-shop system formulated as linear, integer linear and mixed-integer linear programming models. All three models gave different least optimal values, that is, in linear programming, the optimal cost was GHS15.26 with decision variables being continuous (R+) and discrete (Z+). The cost increased to GHS17.50 when the models were formulated as mixed-integer linear programming with decision variables also being continuous (R+) and discrete (Z+) and lastly GHS17.70 for integer linear programming with discrete (Z+) decision variables. The difference in optimal cost for the same problem under different search spaces sufficiently establish that, in programming, the search space undoubtedly affect the optimal value. Applications to most problems like the diet and scheduling problems periodically require both discrete and continuous decision variables. This makes integer and mixed-integer linear programming models also an effective way of solving most problems. Therefore, Linear Programming* is applicable to numerous problems due to its ability to provide different required solutions.

Every construction project requires a plan of construction site, where storage areas, temporary roads, social containers, machinery parks etc. are shown. The location of the machinery park on a building site is very important. Cost is the most important factor for both, civil engineering structures and buildings in terms of the machinery movement. The everyday building machinery transport from the park to the working positions is time and cost consuming. Four possible solution of the location of temporary roads, necessary for such transport of the construction machinery, were discussed. Finding the optimum location of machinery park was presented, and case study calculations were made. Two dimension problem simulation has been applied, enhanced by heuristic algorithms to solve the discussed matter.
