"Akano T.T., Asaolu O.S., Ganiyu R.A., Neye-Akogo C., James C.C.",Process Optimization of Engineering Work Request in an Offshore Environment,2023,"The survival of multinational corporations today and in the future is premised on their competitive edge in effectively deploying modern optimization tools in providing utility and services to clients. This research studies the applications of process optimization in the valve procurement life cycle of the engineering unit of an offshore corporation. A forensic audit into the operations of this multi-disciplinary corporation with varied processes targeted at achieving optimization goals reveals cases of inefficiencies in personnel utilization and cost management. These show up in duplication of personnel effort and inefficient cost burdens. Employing the excellent tools within the lean six sigma framework, analysis of the manufacturers and cost combinations were carried out on 9,145 valves procured between January 2017 and January 2020. The results indicate huge cost variations of over 50% of valve mean price of similar valve types and sizes with resulting loss of cost-saving opportunities for the period under consideration. Process inefficiencies were established, such as unnecessary duplication of the process step of contacting the valve original manufacturer for a quote, inadequate rigour in price negotiation, and unnecessary features requested during valve specification. The outcome of this study corrects these inefficiencies, improves opportunities, and makes recommendations such as the need for all manufacturer engagements to be multi-party that involves the end-user, supply chain group, and approvers to eliminate rework and checkmate opportunities for racketeering. These establish cost-effectiveness and resource efficiency in the system. Copyright © Journal of Engineering, Project, and Production Management (EPPM-Journal)."

"Jacobi S., Hahn C., Raber D.","MasDISPO-xt: Process optimisation by use of integrated, agentbased manufacturing execution systems inside the supply chain of steel production",2009,"The production of steel normally constitutes the inception of many supply chains in different areas of industry. Steel manufacturing companies are strongly affected by bull whip effects and other unpredictable influences along their production chains. Improving their operational efficiency is required to keep a competitive position on the market. Hence, flexible planning and scheduling systems are needed to support these processes, which are based on considerable amounts of data, hardly processable manually anymore. MasDISPO-xt is an agent-based generic online planning and scheduling system for the observation on MES-level of the complete supply chain of Saarstahl AG, a globally respected steel manufacturer. This paper concentrates on the horizontal and vertical integration of influences of rough planning on detailed and the other way around. Based on model-driven engineering business processes are modeled on CIM-level, a service oriented architecture is presented for the interoperability of all components, legacy systems and others wrapped behind services. Finally, an agent-based detailed planning and scheduling ensuring interoperability in horizontal and vertical direction is approached effectively."

"Bai Z., Liu C., Sun H., Ding M.",Complex Service Process Optimization Based on Service Touchpoint Association and the Design Structure Matrix,2021,"Service process optimization is conducive to the innovation of enterprise services, but the poor logic design of multiple touchpoints can easily lead to problems in the service process, such as scattered layouts and repeated paths. Aiming at the promotion of service innovation and user experience, this paper takes the optimization of a single service touchpoint as the prerequisite and proposes a service process optimization method based on service touchpoint association and the design structure matrix (DSM). The association of service touchpoints is categorized into two types, namely, noncoupled and coupled association. The DSM is used to describe the two types of association between service touchpoints, and the matrix operation is used for modular identification and layering of the two kinds of association. Finally, through the above steps, the problematic service process was replanned. By using the service process optimization of a new retail convenience store as an example, the service process is divided into 6 relatively independent modules, and the order of module execution is arranged. Moreover, the optimal service process of the convenience store system is determined, and the method is verified to be feasible. Through optimization both from single service touchpoint and service process modularization, the study provides a reference for process optimization of the complex service system. © 2021 Zhonghang Bai et al."

"AlZu’bi S., Aqel D., Lafi M.",An intelligent system for blood donation process optimization - smart techniques for minimizing blood wastages,2022,"Blood transfusion is a continuous demand, as it is widely required for many medical surgeries and critical operations. Therefore, there is a need to manage the whole process of supplying blood from blood donors to the hospitals and transfusion centers. Many researchers were recently interested in the operations and supply chain management of blood products, they considered the operations and supply chain management of blood products for the purpose of minimizing the blood wastage. As a result of the the inverse relationship between blood donations and blood products demand, more occasional blood shortages can be expected. This research proposes an intelligent system that entails the recruitment of donors that are available to donate blood products on a short notice. The proposed system optimizes the blood donation process by preventing blood shortages and minimizing the wastage of blood units with regards to expiration, and proves promising results. A set of optimization equations have been built for optimizing the process of blood donation to reduce the blood wastage and prevent blood shortage. It considers as well the new insights from the medical literature on the deterioration of stored blood products, as the use of older red blood cells is linked to poorer clinical outcomes. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature."

Prokopova Z.,Raw hide desalting process optimisation,2005,"The presented paper deals with desalting of raw hides, meaning soaking operations viewed from the position of tanner. The process of raw hide desalting is associated with dissolving kinetics of a solid salt adhering to the surface and inside hairy spaces of hide on the one hand, and on transport of sodium chloride ions from the inner volume of hide mass. There are thus two desalting process mechanisms - kinetic, related to dissolving solid surface salt, and diffusion, related to transport mechanisms, i.e. to internal diffusion."

"Choi S.H., Ko J.W., Manousiouthakis V.",A stochastic approach to global optimization of chemical processes,1999,"Chemical process optimization often leads to large nonconvex nonlinear programming problems that have many nonlinear equality constraints. Since the global optimization of such a problem is one of the toughest NP-hard problems, large problems in many cases cannot be solved in a reasonable time span if we rely solely on deterministic algorithms that are theoretically guaranteed to find the global optimum. Generally, stochastic algorithms, which do not guarantee the global optimality of the obtained solution, are suitable for large problems, but not efficient when there are too many equality constraints. Therefore, an algorithm suitable for general chemical process optimization problems is proposed in this paper, which is based on a feasible point strategy and combination of a stochastic global algorithm and a deterministic local algorithm.Chemical process optimization often leads to large nonconvex nonlinear programming problems that have many nonlinear equality constraints.

Mueller C.,"Process optimization in mining: Preconditions, step-by-step implementation and benefits",2015,"Enhancing the efficiency in underground mining is crucial to keep the operations profitable especially in times of low product prices. Up to now, the increase of operational efficiency and productivity mainly originated from mechanization and automation. However in most cases today, the incremental cost in any further step of mechanization and automation are so high, that often the amortization is questionable. At the same time, the utilization of the valuable equipment working in the mine still is relatively low compared to other manufacturing or process industries. These industries already have demonstrated the next big step in efficiency increase: The optimization of the operational processes in the entire factory to increase production at the lowest possible cost. Process Optimization therefore also in mining has the biggest potential to perform the next big step in productivity increase in order to keep competitive even at low commodity prices. Implementing Process Optimization first of all means to gather usable information (not raw data) from the process in real time and to process as well as to visualize this information in a way so the process managers are able to make instant decisions with the goals of minimizing the monetary impact of an unexpected happening in the mine and maximizing the production output. During the ""OPTI-MINE"" project funded by the European Union's RFCS program during 2011-2014, the application of process optimization technologies was successfully demonstrated in different aspects in five European coal mines. This paper focuses on the benefits and implementation of process optimization projects for underground mining and the importance of seamless communications as a precondition so the benefits can be proven already after comparatively small implementation steps with limited investments using the examples from the OPTIMINE project."

"Espinosa E., Pacheco E.",Online simulation for logistics and decision making,2007,"Traditional training for IT-professionals is substantially unsynchronized with that of a Business Process Management (BPM) professional, even though their respective fields of expertise are supposed to be placed along a continuum. This causes that the simulation, and later implementation, of dynamic supply chains, is not delivered in a realistic way, especially when business decisions are based on process optimization that features capabilities (what?) and orchestrations (how?), but the underlying structure and metrics are not in sync with business simulations. We present ongoing research that aims at covering the interactions between companies, emphasizing the interactions between methods typically associated with particular fields such as order fulfillment, parts and service support, or industrial packaging. We have developed an online Logistical Simulator (LOST) and have tested it with undergraduates and professionals in continuing education. We present the basic method for presenting and playing with variables and the preliminary conclusions of our work. © 2007 IEEE."

"Prickett P., Davies G., Grosvenor R.",The development of a knowledge-based electricity power station condenser management system,2012,This paper presents an approach to the monitoring one of the most critical elements of plant functioning within an electricity power station. It centres on research aimed at improving the efficient operation of the condenser stage of the generation cycle. This utilises the process optimisation data supplied by the condenser manufacturer in combination with the control signals issued by the programmable logic controller to manage the plant. The condenser performance data is transformed into an embedded algorithm and the PLC data is made available via the SCADA interface. The approach demonstrates how knowledge-based management systems can be engineered by utilizing the readily available SCADA functionality. © 2012 The authors and IOS Press. All rights reserved.

Ng C.Y.,Business process optimization using the ant colony system,2018,"Process optimization is a key consideration in workflow management. Implementing an efficient workflow may improve customer satisfaction and enhance productivity of an enterprise. Many optimization tools have been introduced to solve scheduling problems in the manufacturing environment, but most of them have not drawn much attention of decision makers for workflow analyses. This is mainly due to the difference between business operations and manufacturing processes that the process optimization tools cannot be directly applied for analyzing business workflows. Scholars have associated the attributes of workflow in the business environment with those of scheduling concepts to facilitate the use of job shop scheduling techniques for solving workflow problems. However, there is still not much discussion on the use of metaheuristic algorithms for workflow analyses. This paper proposes the use of a systematic approach that entails the ant colony optimization algorithm for identifying the best task sequence in support of processing time analyses. The applicability of the proposed approach is demonstrated with a case example. The result shows that a better operation sequence in terms of shorter processing duration can be obtained by the proposed approach. Copyright © 2018 John Wiley & Sons, Ltd."
