Abstract. This study is motivated by the fact that inventory management problem is focused throughout the industrial firms nowadays as well as inventory management problems are not easy to be appropriately solved. According to the concept of systems approach can better give more effective result especially when applied to complex problems. In this paper, we propose a systems thinking framework for solving real-world inventory management problems. The systems thinking framework comes with three case studies to enhance better understanding of how to apply the framework with problems. This study aims to bring about the ideas for solving inventory management problems in more practical fashion. In addition to benefit the development of the proposed framework, the instructors and the industrial firms will gain the high-performing students or workers, who can get to the point of problem and can propose the reasonable solution to effectively dealing with problems. Moreover, this study can be used as a guideline for engineering educators to develop other meaningful methods in advances. We expect that if the case studies are collected much enough, the knowledge-based system for solving inventory management problems can be built for easy investigation to whom have the interest in solving inventory management problems.

“…Usually, this kind of problem is solved using trade-off or compromised with optimization method which cannot eliminate the source of noise completely and will need a filtering system in the latter state. It is the first time, also to the best of our knowledge, that this contradictory requirement is overcome without compromise by deploying the principle of separation in TRIZ [18] by generating low reference voltage during expiration period and high reference voltage outside expiration period. This prevents errors from unstable expiration breath sound during expiration period and evades noise and artefact during inspiration and pause period as shown in Fig.…”

“…This situation is called "Inventive situation" in the Theory of Inventive Problem Solving (TRIZ) [16] which states that in order to attain an ideal solution, contradiction must be overcome with no trade-off or compromising by utilizing resources within or in the environment of the system at no or little cost [17]. This kind of contradiction is called physical contradiction and the solution ideas can be generated by principle of separation which is divided into separation in space, in time, in system, and by condition [18]. In this case, it is more practical to generate ideas from the concept of separation in time, that is Vref must be low during expiration period and Vref must be high during inspiration and pause period.…”

In this paper, we propose a novel approach to respiratory rate measurement using resonance tube to enhance the performance of microphone inserted and fixed at the end of the tube to catch breath sound signal from the mouth and/or nose. The signal is amplified and passed into envelope detector circuit after which it is compared with a suitable reference voltage in comparator circuit to generate a pulse train of square wave synchronized with the respiratory cycle. A simple algorithm is developed in a small microcontroller to detect rising edges of each consecutive square wave to calculate respiratory rate together with analysis of breathing status. In order to evade noises which will cause errors and artifacts in the measuring system, the reference voltage is creatively designed to intelligently adapt itself to be low during expiration period and high during inspiration and pause period using the concept of resolving contradiction in the theory of inventive problem solving (TRIZ). This makes the developed device simple and low-cost with no need for complicated filtering system. It can detect breath sound as far as 250 cm from the nose and can perform accurately as tested against End Tidal CO2 Capnography device. The result shows that the developed device can estimate precisely from as low as 0 BrPM to as high as 98 BrPM and it can detect shallow breathing as low as 10 mV of breath sound.

Many companies use various problem-solving processes to solve problems in the field. However, familiar problem solving processes are used or standardized problem solving processes are used. As a result, companies are having difficulty resolving the numerous types of problems that arise.To improve these problems, the S-Cube method, which combines the advantages of various problemsolving methodologies, was developed and applied to the field. Its characteristics are a problem-solving methodology that pursues simplicity, speed, flexibility, differentiation, standardization, and synergy. In particular, tasks were classified by type and systemized to obtain ideal results by applying a problemsolving process appropriate for each type. By introducing the core concept of TRIZ, we proposed a method of finding contradictions in problems and deriving innovative solutions. In addition, a problemsolving methodology was developed by distinguishing problem types during the task selection stage. And, through examples, it was simply applied in the field through S-Cube. As a result, there was an improvement of about 60% in problem solving speed and by applying S-Cube. Additionally, we were able to secure the knowledge of our members in the semiconductor field. In addition, by introducing and developing a new problem-solving process, a guide was presented to industrial sites to perform tasks more efficiently using a problem-solving methodology.
