Multiple Project Portfolio Scheduling Subject to Mass Customized Service

Declarative framework enabling to determine conditions as well as to develop a decision making software supporting small and medium size enterprises aimed at unique, multi project-like and mass customized oriented production is discussed. The set of unique production orders grouped into portfolio orders is considered. To each production order treated as an activity network common shared resources operation times of which are known in advance are allotted. The problem concerns of scheduling of a newly inserted projects portfolio subject to constraints imposed by a multi-project environment The answer sought is: Whether a given portfolio can be completed within assumed time period in a manufacturing system in hand? The goal is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multi project-like and mass customized oriented production scheduling. The attached calculation example illustrates the computational efficiency of the proposed solution.

Digraphs Minimal Realisations of State Matrices for Fractional Positive Systems

This paper presents a method of the determination of characteristic polynomial realisations of the fractional positive system. The algorithm finds a complete set of all possible realisations instead of only a few realisations. In addition, all realisations in the set are minimal. The proposed method uses a parallel computing algorithm based on a digraphs theory which is used to gain much needed speed and computational power for a numeric solution. The presented procedure has been illustrated with a numerical example.

Optimisation of Digraphs-Based Realisations for Polynomials of One and Two Variables

This paper proposes a set of modifications to the algorithm proposed earlier, that finds a complete set of minimal solutions for the characteristic polynomial on basis of digraphs theory and parallel computation. Changes proposed allow for parallelisation of previously sequential part of the algorithm, accurate estimation of number of solutions created and speed-up of both parts of the algorithm. Reduction of algorithm’s complexity is greatest for monomials consisting of only one variable and for one-variable polynomial a complete set of minimal solutions can be found as fast as in linearithmic time.

SysML Modeling of Functional and Non-functional Requirements for IEC 61131-3 Control Systems

Control software performs important roles in various branches of industry. Its complexity and importance are still growing, thus it is crucial to provide engineers with new methods to improve its quality. One of possible solutions is modeling, which could be introduced into the overall development process. The paper proposes an approach to modeling of requirements dedicated to control systems developed according to the IEC 61131-3 standard. Such a solution supports four kinds of requirements. The first group specifies expected behavior of Program Organization Units (POUs, namely programs, function blocks, functions, and classes). The other two present performance requirements oriented towards POU execution and communication between devices in Distributed Control Systems (DCSs). The last type is dedicated to displays in a Human-Machine Interface (HMI) and specifies their expected operation. The proposed approach has been introduced in the CPDev engineering environment for programming various kinds of controllers.

Analysis and Modelling of Magnetic Circuits in Magnetic Shape Memory Alloy Actuators

Authors presented in article modeling of magnetic circuit for magnetic shape memory alloys. These alloys are a new class of smart materials which can generate strains and force in external magnetic field. Thus that properties MSMA fill gap between classical SMA and magnetostrictive materials. As a drawbacks strong nonlinearities should be mentioned: wide asymmetric hysteresis loop, thermal sensitivity, first cycle effect. Very high flux density need for effective operation over the whole range strongly affects on size of the magnetic circuit. Mathematical modeling does not allow for design optimal shape of core. Authors aided their work by FEA of magnetic flux in core. Computed results were compared with magnetic induction measured on prepared test bench.

Characteristics of the Improved Magnetic Shape Memory Alloy Actuator Test Stand

The article describes improved magnetic shape memory alloy actuator (MSMA actuator) test stand and the previously made stand. There are pointed weak sides of the first stand and the improvements in the new one. Several quasi-static measurements were performed and results were compared between both measurement stands. The MSMA actuator characterises with significant hysteresis loop, but improved test stand allowed to reduce its width. The increased rigidity of the stand excluded influence of stand deformations on the results. The described stand resulted with similar but improved measurements of the MSMA actuator characteristics, which also proved the correctness of the previous results.

A Hybrid Approach to Sustainable Supply Chain Optimization

This paper describes the hybrid approach to optimization of decision problems in sustainable supply chain (SSC). The hybrid approach proposed here combines the strengths of mathematical programming (MP) and constraint logic programming (CLP), which leads to a significant reduction in the search time necessary to find the optimal solution, and allows solving larger problems

.

The hybrid method appears to be not only as good as either of its components used independently but in most cases it is much more effective. The simplified models of cost optimization presented in the article illustrate the advantages of the approach. For these models, the use of hybrid approach allows obtaining optimal solutions ten times faster.

New Approach to Automation and Robotics Vocational Education in Support of Europe Reindustrialization

The post-industrial Europe cannot effectively fight the economic crisis. The Europa 2020 strategy goal is the advancement of the European Union economy which would be impossible without re-industrialisation. To reverse the declining role of industry, the re-industrialisation will notably be based on SMEs in which the production processes are not automated enough. In result the existing, as well as new companies will invest significant efforts in Automation and Robitisation (A&R) to minimise costs by eliminating manual work. The article presents the approach for preparation of the new generation vocational courses tailored especially to meet the needs and expectations of small and medium enterprises connected with introduction of new technologies, especially connected with Automation and Robotisation.

Application of Jiles-Atherton Model for Modelling Magnetization Characteristics of Textured Electrical Steel Magnetized in Easy or Hard Axis

Paper presents the results of application of extended Jiles-Atherton model for modeling of the magnetic hysteresis loops of anisotropic, grain oriented Unisil M130-27s silicon electrical steel. During the modeling both anisotropy of the magnetic material as well as changes of average energy required to break pinning site were considered. Moreover, equation determining anisotropic anhysteretic magnetization was corrected to be coherent with isotropic model. Parameters of the model were determined during the evolutional strategy-based optimization process simultaneously considering six hysteresis loops measured for different value of amplitude of magnetizing field as well as for magnetization in direction of the easy and hard axis of the magnetic material. Source code for this process is available at the web page. High level of agreement between experimental results and results of modeling was achieved and confirmed by the value of coefficient of determination. Simultaneous determination of Jiles-Atherton model parameters based on six hysteresis loops enables successful assessment of average anisotropy energy density during the optimization process. Moreover, set of nine Jiles-Atherton model’s parameters is suitable to model functional characteristics of the magnetic core made of silicon electrical steel necessary for numerical optimization of construction of electric and electronic devices.
