  1. DISCRETE-EVENT SIMULATION (DES) Business processes are commonly modeled as computer-based, dynamic, stochastic, and discrete simulation models. The most popular way to represent these models within the computer is using Discrete-Event Simulation (DES). In simplistic terms, DES defines how a system with discrete flow units or jobs evolves. Technically, this implies that the computer tracks how and when state variables such as queue lengths and resource availabilities improve over time—the state-variables change due to an event (or discrete event) occurring in the system. A characteristi
  2. Fault Injection: Overview In Fault Injection experiments, various faults are injected into a simulation model of the target system or a hardware-and-software prototype of the system. The behavior of the system in the proximity of each fault is then observed and classified. Parameters that can be considered based on such experiments include the probability that a fault will create an error and the probability that the system will successfully perform the actions required to recover from that error. These actions consist of recognizing the fault, identifying the system component i
  3. Mind Mapping: The Swiss Army Knife for the Brain Mind Mapping is a technique used to capture and articulate ideas and thoughts in a fashion that resembles how our minds process information. It is a handy collaboration tool that summarizes ideas and thoughts generated on complex concepts or problems in a simplified and consolidated structure, thereby facilitating creative problem solving and decision making. It helps explore relationships between the various aspects of a problem and inspires creative and critical thinking. Mind mapping involves capturing thoughts and ideas in a non
  4. Smart Little People ( SLP ) Smart Little People is a simple TRIZ Creativity tool developed from the observation of innovative and creative people at work. This powerful tool is often mastered in a short period. Smart Little People are tiny imaginary beings who represent the various elements of the matter we try to understand and solve. It works as a mental trick because it’s supported empathy or creating some personal analogy with the case. Compassion means becoming the object/problem and looking out to determine what will be done from its position and viewpoint. If we imagine ourselves b
  5. What is Business Process Re-engineering (BPR)? The complexity associated with any new business model is often staggering. Many organizations tend to miscast tactics or speculate meanings. Hammer and Champy provide the most extensively used definition for Business Process Reengineering (BPR) in their best-selling book "Re-engineering the Corporation" which reads as follows; "The fundamental re-thinking and radical re-design of business processes to achieve dramatic improvements in contemporary critical measures of performance, such as cost, quality, service, and speed." How to sele
  6. What is Just in Time? Just-in-time (JIT) manufacturing, also known as the Toyota Production System (TPS) or Just-in-time production, is a management philosophy that primarily reduces times within the production system and response times from suppliers' customers. The advantages of a Just-in-time (JIT) system The following are some of the advantages that gain through the implementation of Just-in-Time: Reduction in order to payment timeline Reduction in Inventory costs Reduction in space required. Reduction in handling equipment and other costs Le
  7. What is a Water spider (or Mizusumashi) The Water Spider (“Mizusumashi”) System is one of the improvement specialties in internal logistics flow. This Japanese word indicates “water beetle,” and this internal logistics worker is often called a “water spider” in English. This term probably was chosen for this concept because of the water beetle’s agility as it swims across the water. Here a mizusumashi is a logistics worker who does the internal transportation of goods using a standard fixed cycle route. The Water Spider is a critical element of the creation of internal
  8. What is Class imbalance? Data are assumed to suffer the Class Imbalance Problem when the class distributions are incredibly imbalanced. In this connection, many classification learning algorithms have moderate predictive accuracy for the uncommon class. Cost-sensitive learning is a general approach to solve this problem. Class imbalanced data-sets occur in much real-world applicability where the class distributions of data are highly imbalanced. However, in the two-class case, we can assume that the minority or rare class is a positive class without losing generality. The majo
  9. The Golden Ratio is a mathematical ratio found almost anywhere, like nature, architecture, painting, photography, and music. When applied to design specifically, it creates an organic, balanced, and aesthetically-pleasing composition. The Golden Ratio is derived when we divide a line into two parts and the longer part (a) separated by, the smaller section (b) is equal to the sum of (a) + (b) divided by (a), which both equal to 1.618. This formula helps us to create shapes, logos, layouts, and more. Using the same idea, we can create a golden rectangle. The below diagram
  10. What is a Block Diagram? A block diagram is a specific, high-level flowchart utilized in engineering, hardware design, electronic design, software design, and process flow diagrams. It is used to design innovative systems or to describe and enhance existing ones. The block diagram represents, at a sketch level, how a process flows from function to function or from unit to unit within an establishment. The diagram uses blocks to reflect the essential activities and links them together by connecting lines representing elements or communication flows. Essential Components of a Block Dia
