In this article we will discuss and talk about how the Kaizen technique came about, how it was updated over time, as well as exemplifying how this technique came to transform and reform the industrial production line. From it, it was possible to help the search for better results in the companies, since its implementation is totally correlated to the focus on cost reduction and the good performance of the production line and, consequently, in obtaining effective profitability of the company. Posteriorly, we will exemplify how the technique is used in a company that operates in the plastic transformation and production segment.

Automation industries are trying to integrate and consolidate the operation of various processes that make up their production line. Most often, every one of those processes is controlled by unique controllers and hardware as the process demands. Each of these independently controlled units can be seen as “islands of automation”. It is indeed a challenge for the control engineer to ensure smooth communication between these islands. The challenge gets magnified many fold when the plant performs troubleshooting, maintenance, or an upgrade. Compatibility over time, between components that make up the line can never be guaranteed in today’s world dominated by software drivers where improvements and upgrades are frequent. It is generally agreed in the industry that controllers and software consolidation should be done as much as possible. In this paper, the authors would like to discuss the case of integration of two such islands of automation, i.e. motion control (traditional single axis control of servos) and robotics. Automation integrators working on applications such as packaging, converting, palletizing etc. use a combination of robots and independently acting servos to achieve their objective. Programming software and programming methods for these two elements have been quite different. There has been a push in the automation industry to consolidate the control programming of motion components and robots because the underlying control techniques that actuate motion are the same. However, there are challenges that must be overcome in order to ensure that this push brings about useful and substantial changes that reduce control programming, maintaining and troubleshooting efforts. Such challenges are listed in this paper. Potential solutions to overcome these challenges are also laid out in this work.

PurposeThis study aims to create a reliable, collaborative and sustainable business environment with suppliers of a company for providing high-quality and low-cost products on time. A supplier management system that sustains existing suppliers by sharing work based on systematic performance evaluation while developing the supplier base with potential suppliers is proposed.Design/methodology/approachBuilt on quantitative approaches, supplier management functions are integrated in the designed system. A quantitative strengths, weaknesses, opportunities and threats (SWOT) analysis is adapted for evaluating potential suppliers. A multi-objective integer linear programming (ILP) model is developed for the distribution of orders among selected potential and existing suppliers. A performance evaluation scheme based on an exponentially weighted moving average (EWMA) is proposed to evaluate and monitor suppliers' performance over time.FindingsProposed system develops a supplier base by methodically selecting and approving new suppliers, and a sustainable relationship with both new and existing suppliers is established based on performance over time. Decisions on retaining or removing suppliers from the base are objectively made by quantitative evaluations. Orders are fairly distributed among suppliers under the constraints imposed by the management. Dependence on a certain set of suppliers and its associated risks are reduced while agility in offering goods is enabled.Originality/valueBusiness processes for selecting new suppliers, distributing orders among all suppliers, evaluating and monitoring performance over time are quantitatively integrated to add value in operational decision-making. The proposed system is original in the holistic approach for managing and sustaining multiple suppliers of a company based on performance.

This chapter examines in particular the valuation of banks which can be classified into five parts. It introduces several valuation approaches to find out whether there is a superior method. This chapter starts with a description of bank regulations and their impact on bank valuations and continues with an overview of valuation approaches. The second part applies the banking sector decision Models. The third section shows banking sector valuation models. The fourth part presents the input factors that are needed to value a company. In the last part, financial statements have been used to analyze the main ratios of the Bank of America, and the calculated values were then compared over time (2014-2018) to assess the explanatory power of the bank.

The chief justice is not mentioned in the judicial article of the Constitution (Article III), but “The chief justice” demonstrates how the role has grown in importance over time. It is a multifaceted role, like that of a chief executive of a company. A traditional legal background is not necessarily the best preparation. Some chief justices believed that casting one of the nine votes in a case is still one of their most useful functions. It was a chief justice, William Howard Taft, who decided that the Supreme Court’s caseload should be decided on a discretionary basis, putting the Court in a position to dictate America’s legal agenda.

Over Time

While access to reliable electricity can significantly constrain industrial production, little is known as to how unreliability impacts firm level productivity. This is a particularly salient issue for firms in developing countries, where electricity provision is still unreliable and self-generation is costly. This paper analyzes the impact of electricity provision on productivity, instrumenting for electricity demand with district level solar irradiance. Results indicate that firms exhibit decreasing productivity in the initial stages of electricity adoption that decreases over time. Furthermore, I find that unreliability negatively impacts productivity initially and over time, and this effect is larger for smaller firms.

Some Considerations for Investors Exploring ESG Strategies

Investors who are concerned about environmental, social, and governance (ESG) factors face numerous questions. In the author’s opinion, investors need to determine which ESG issues are important for them, and how these issues should be reflected in a portfolio. For some strategies, ESG factors are integral to the investment process, whereas for other strategies, ESG factors are best captured via simple and transparent rules (screens and/or tilts). Investors also face several practical implementation choices. Should each company be evaluated on the basis of its current ESG profile, or is the trend more relevant? Should a company be analyzed on a stand-alone basis or relative to its industry peers? And for the strategy, what is the appropriate level of active risk (tracking error) relative to the policy benchmark? In addition, investors need to determine how to monitor any ESG strategy over time, which will help ensure the strategy is performing as expected. In the author’s opinion, perhaps the biggest challenge facing investors is articulating an investment thesis for an ESG strategy. Which ESG factors are already reflected in security prices, and which ESG factors have the potential to drive outperformance? Finally, the article identifies some differences between equity and fixed income strategies as they relate to ESG.

We analyze the relations between ethnographic data and theory through an examination of materiality in research practices, arguing that data production is a form of material theorizing. This entails reviewing and (re-)applying practice-theoretical discussions on materiality to questions of ethnography, and moving from understanding theory primarily as ideas to observing theorizing in all steps of research practice. We introduce “pocketing” as a heuristic concept to analyze how and when ethnographic data materializes: the concept defines data’s materiality relationally, through the affective and temporal dimensions of practice. It is discussed using two examples: in a study on everyday architectural experience where ethnographic data materialized as bodies affected by architecture; and in a study on digital cooperation where research data’s materialization was distributed over time according to the use of a company database. By conceptualizing data’s materiality as practice-bound, “pocketing” facilitates understanding the links between data and theory in ethnographic data production.

How can risk of a company be allocated to its divisions and attributed to risk factors? The Euler principle allows for an economically justified allocation of risk to different divisions. We introduce a method that generalizes the Euler principle to attribute risk to its driving factors when these factors affect losses in a nonlinear way. The method splits loss contributions over time and is straightforward to implement. We show in an example how this risk decomposition can be applied in the context of credit risk.
