Opis:
Grammatical Evolution (GE) is a form of Genetic Programming (GP) based on Context-Free Grammar (CF Grammar). Due to the use of grammars, GE is capable of creating syntactically correct solutions. GE uses a genotype encoding and is necessary to apply a Mapping Process (MP) to obtain the phenotype representation. There exist some well-known MPs in the state-of-art like Breadth-First (BF), Depth-First (DF), among others. These MPs select the codons from the genotype in a sequential manner to do the mapping. The present work proposes a variation in the selection order for genotype’s codons; to achieve that, it is applied a random permutation for the genotype’s codons order-taking in the mapping. The proposal’s results were compared using a statistical test with the results obtained by the traditional BF and DF using the Symbolic Regression Problem (SRP) as a benchmark.

Opis:
Grammatical Evolution (GE) is a novel data-driven, model-induction tool, inspired by the biological gene-to-protein mapping process. This study provides an introduction to GE, and demonstrates the methodology by applying it to construct a series of models for the prediction of bankruptcy, employing information drawn from financial statements. Unlike prior studies in this domain, the raw financial information is not preprocessed into pre-determined financial ratios. Instead, the ratios to be incorporated into the classification rule are evolved from the raw financial data. This allows the creation and subsequent evolution of alternative ratio-based representations of the financial data. A sample of 178 publicly quoted, US firms, drawn from the period 1991 to 2000 are used to train and test the model. The best evolved model correctly classified 86 (77)% of the firms in the in-sample training set (out-of-sample validation set), one year prior to failure.

Opis:
The aim of the paper was to improve service processes carried out by Knorr-Bremse Systemy Kolejowe Polska sp. z o.o. Particularly, emphasise unnecessary movements and physical efforts of employees. The indirect goal was to find a solution in the simplest possible way using the Muda ideology. In order to improve the service process at the beginning was executed the process mapping for the devices to be repaired, ie. brake callipers, electro- hydraulic units and auxiliary release units. The processes were assessed and shown as Pareto-Lorenz analysis. In order to determine the most time consuming process. Based on the obtained results use of a column crane with articulated arm was proposed to facilitate the transfer of heavy components between areas. The final step was to assess the effectiveness of the proposed solution in terms of time saving. From the company perspective results of the analysis are important. The proposed solution not only reduces total service time but also contributes to crew’s work comfort.

Opis:
Modern information management systems are often driven by workflow engines, which require an accurate, detailed, and structured process description. Instead of theoretical modelling of such processes we propose a technique which can be a connection between traditional management (organisational structure) and business process management approach. In our work we present a case study where the automatic process mining techniques are applied to administrative processes in an environment of event logs recorded by DMS. We use event log data to discover and describe the process map of the organisation and to model structured process descriptions. Our approach allows for the extraction of models based on facts and it is a direct connection between the process model and raw data generated by the organisation. Such scenario increases consistency between the mapped model and the reality of the organisation.

Opis:
Supply chain can be considered as a series of linked inventories. This paper considers the impact of inventory on the economics of the businesses and the whole chain and discusses causes of inefficiency. In most supply chains the goods are inactive for the majority of the time, and this leads to longer term and therefore less accurate forecasting. The result is typically excess inventory, shortages, and inflexibility. By analysing the wasted time and costs in the supply chain, a clearer view of the whole process can be created. Total supply time can be considered as three components, namely value added time, non-value added process time, and waste time. This basic approach shows where improvements should be focussed. Using this time-based measurement enables more relevant comparison between supply chains than the normal supply chain efficiency ratio.

Opis:
The sales market requires both the highest quality of offered goods and satisfactory prices for the buyer. In addition to the reliability of the important aspects are also the time of order fulfillment, reliability, readiness to act around the clock, and service of sold goods after their sale. In the production and confection of conveyor belts, the priority is a customer who, having strictly defined product requirements, also has individually focused goals. To meet these aspects, you need to look after the product both during its production and after. The products of this industry are specific, so that they can be used, after sales service is often required to be installed at the customer and possible actions to maintain their good condition during operation. The article analyzes selected production processes of transmission belts to identify disturbances. The analysis uses the value stream mapping method. Then, improvement methods were proposed.

Opis:
The visual management technique used in process improvement, i.e. value stream mapping (VSM) has been presented in the paper. Value stream mapping is one of the basic management tools in the context of Lean Management or Lean Production. It allows to visualize the flow of decision, information, material and their connections in the full production cycle (from the order, through planning, production, to shipping to the customer). VSM is a lean tool that gives the ability to create flows in the process before implementing changes. In this paper, the possibilities of changes planning based on the current and future status maps have been discussed. On the basis of the current state map (CSM), the areas requiring improvement and operations which efficiency is decisive and for the process have been designated. Particular attention has been paid to the possibilities of using VSM in unit production processes. In the paper has been proposed the two possibilities for company development in terms of the improvement technique in line with the Kaizen philosophy as well as the implementation of process innovations. Which means balanced development through the improvement of the existing process or an acute development strategy through the implementation of process innovations (which involves significant costs).

Opis:
The relatively limited application of lean in the food process industries has been attributed to the unique characteristics of the food sector i.e. short shelf-life, heterogeneous raw materials, and seasonality. Moreover, barriers such as large and inflexible machinery, long setup time, and resource complexity, has limited the implementation and impact of lean practices in process industries in general. Contrary to the expectations in the literature, we bring in this paper a successful experience of lean implementation in a company of the food-processing sector. By focusing on two lean tools (VSM and SMED), the company reduced changeover time by 34%, and increased the production capacity of the main production line by 11%. This improvement enabled the company to avoid the use of temporary workers by extending the worktime of its workforce during peak months. Moreover, the reduction of setup time avoided the use of large lot size in production, which, in turn, reduced the total cycle time of production and the incidence of quality problems.

Opis:
Let \(C\) be a bounded, closed, convex subset of a uniformly convex and uniformly smooth Banach space \(X\). We investigate the weak convergence of the generalized Krasnosel'skii-Mann and Ishikawa iteration processes to common fixed points of semigroups of nonlinear mappings \(T_t\colon C \to C\). Each of \(T_t\) is assumed to be pointwise Lipschitzian, that is, there exists a family of functions \(\alpha_t\colon C \to [0, \infty)\) such that \(\|T_t(x) - T_t (y)\| \leq\alpha_t (x)\|x -y\|\) for \(x, y \in C\). The paper demonstrates how the weak compactness of \(C\) plays an essential role in proving the weak convergence of these processes to common fixed points.

Opis:
The article presents the essence of the method of value stream mapping on the example of a selected production process in an automotive company. The analysis presented in the paper concerned the indication of potential organizational possibilities of actions aimed at implementing changes in the organization based on the results of measuring the process with the use of the OEE (Overall Equipment Effectiveness) indicator. All stages of the production process were explained, which allowed to obtain the results of the process efficiency analyses. Further on, the results of the analysis of process improvement in accordance with the PDCA approach are discussed. The significance of establishing the method in order to improve the functioning of the process and the meaning and usage of the value stream mapping methodology in building successful relations with the end customer were emphasized. The undertaken activities constitute a research gap defined as follows: the effectiveness of management methods in an organization depends on the efficiency of using the applied indicators and reacting to changes. Thus, defining models with potential application capabilities in order to increase management effectiveness is one of the most important issues in the area of enterprise organization.
