Which Management Control System principles and aspects are relevant when deploying a learning machine?

Martin, Johansson, Mikael, Göthager January 2017 (has links)
How shall a business adapt its management control systems when learning machines enter the arena? Will the control system continue to focus on humans aspects and continue to consider a learning machine to be an automation tool as any other historically programmed computer? Learning machines introduces productivity capabilities that achieve very high levels of efficiency and quality. A learning machine can sort through large amounts of data and make conclusions difficult by a human mind. However, as learning machines become even more complex systems, they introduce an uncertainty not previously considered by automation tools. The algorithms can make their own associations, and the automation engineer will no longer know exactly how a learning machine produces its outcome. What is the motive for a learning machine’s decision? A learning machine in this context becomes more human-like compared to the older generation of automation computers. This thesis concludes that most contemporary Management Control System principles are relevant when deploying machine learning, but some are not. A Management Control System must in contradiction to a historically programmed computer, consider multiple human-like aspects while controlling a deployed learning machine. These conclusions are based on empirical data from web-articles, TED-talks, literature and questionnaires directed to contemporary companies using machine learning within their organizations.

Förbättring och effektivisering av lagerhantering

Mirzaie Shra, Afroz, Vu, Felix January 2017 (has links)
The following thesis is based on a study on warehousing for an inventory of finished goods at Volvo Construction Equipment in Eskilstuna.   The inventory stores components consisting axles and transmissions. The project portrays a current situation analysis based on collected primary data, in form of interviews and observations. The current situation analysis includes a detailed process mapping, different warehouse layouts along with calculations. These aspects have been used in the development of improvement propositions.   The company is currently required to deliver components according to FIFO (First In, First Out), that is therefore fundamental when designing the following thesis. The project has however not been based on implementing FIFO, but only improving the existing management of FIFO. The current way of working with FIFO at the company is not ideal, consequently contributed to lack of storage space. This has eventually led to some components being stored outside the warehouse. It means that the components will not be weather-protected, which is one of the aspects that the company wishes to improve.   The Authors have presented various improvement propositions consisting investing in a: pallet, mobile- and a push back racking system and an improved inventory layout. These suggestions have been compared based on various factors that could be prioritized by the company. Examples on these key factors are: cost, volume utilization and enforcement of FIFO. The cost analysis for the racking systems are based on assistance from suppliers that has led to an enhanced cost comparison. The presented propositions have been delimited to ultimately being able to decide the final suggestion. For further studies, the company is recommended to invest in a pallet racking system, which is not only a beneficial economical solution, but also solves space shortage while all the components are stored with weather- protection. This will ultimately lead to improvement on managing FIFO in the finished goods inventory that the company strives after. / Detta examensarbete är grundat på undersökningar inom lagerhanteringen i färdigvarulagret (FVL) på Volvo Construction Equipment i Eskilstuna.   Färdigvarulagret lagerhåller i dagsläget komponenter bestående av axlar och transmissioner. Detta arbete redogör en nulägesbeskrivning som har tagits fram med hjälp av insamlad primärdata, i form av intervjuer och observationer. Nulägesbeskrivningen innefattar bland annat en detaljerad processkartläggning, olika lagerlayouts samt beräkningar som har varit fördelaktigt vid framtagandet av förbättringsförslagen. Den insamlade primärdata har jämförts med den teoretiska referensramen, som har varit till stöd vid utformningen av förslagen.   Företaget har i dagsläget krav på att leverera komponenter enligt FIFO (First In, First Out), som därmed är grunden till examensarbetet. Detta arbete har inte utgått från att implementera FIFO, utan att endast förbättra den befintliga hanteringen. Dagens arbetssätt av FIFO är inte optimal, i och med att det har bidragit till platsbrist i lagret. Detta har lett till att vissa komponenter lagerhålls i ett utelager som är placerat utanför FVL. Komponenterna som lagras i utelagret blir inte väderskyddade, vilket är en av de faktorer som företaget vill lösa.   Författarna har tagit fram olika förbättringsförslag bestående av införandet av ett: mobilt-, pall och rullfackställage, eller en ny lagerlayout. Dessa förslag har jämförts utifrån olika faktorer som författarna anser att företaget bör prioritera. Exempel på väsentliga faktorer som förslagen innefattar är bland annat kostnadsaspekten, volymutnyttjandet och tillämpningen av FIFO. Kostnadsförslagen för lagersystemen är framtagna utifrån stöd från leverantörer, vilket lett till en tydligare kostnadsjämförelse. Utifrån de presenterade förbättringsförslagen, har dessa avgränsats för att till slut kunna komma fram till ett slutgiltigt val. Vid fortsatta studier kring arbetet rekommenderas företaget att investera i ett pallställage som inte endast är en ekonomisk lösning, utan som dessutom löser platsbristen i lagret. Samtidigt lagerhålls samtliga komponenter med väderskydd. Detta kommer slutligen leda till en förbättrad FIFO hantering i FVL som företaget eftersträvar.

A Control System for the E-Linac View Screen System

Abernathy, Jason Matthias 21 December 2015 (has links)
The TRIUMF view screen system encompases a set of devices which individually image, and produce measurements of, the transverse profile of an accelerated electron beam. A control system is an essential component of the overall diagnostic device. The system requirements were compiled from those produced by the TRIUMF laboratory and from those based on the needs of the individual diagnostic devices. Based on the requirements, a control system was designed and implemented with a combination of industrial electrical and mechanical hardware, and a variety of software components. One component of the image reconstruction algorithm was validated with experimental data; the accuracy and precision of beam profile measurements was evaluated through simulation studies. Although it was not possible to demonstrate the satisfaction of requirements relating to alignment, it was shown that all other requirements were satisfied. / Graduate / 0798 / 0752 / 0605

Är man stor måste man vara snäll : En fallstudie i hur ICA Gruppen och MAXI-butiker samverkar i hållbarhetsarbetet / With great power comes great responsibility : A case study research on how ICA Gruppen and MAXI stores interact concerning sustainability efforts

Cragfors, Kerstin, Holmgren, Anna, Johansson, Cajsa January 2017 (has links)
Frågeställning: Vad motiverar ICA Gruppen respektive MAXI-butikerna till hållbarhetsarbete och hur skiljer sig deras hållbarhetsmål åt? Hur integreras ICA Gruppens hållbarhetsarbete i de olika MAXI-butikerna? Vilka strategier kännetecknar ICA Gruppens och MAXI-butikernas hållbarhetsarbete? Syfte: Syftet med uppsatsen är att beskriva samverkan mellan ICA Gruppens och mellansveriges handlarägda MAXI-butikers hållbarhetsarbete. Metod: Denna kvalitativa uppsats med en abduktiv ansats, baseras på primärdata från fem separata intervjuer med chefer från fyra olika MAXI-butiker och en hållbarhetsansvarig på ICA:s huvudkontor. Förutom intervjuer har vetenskapliga artiklar med relevanta teorier, forskningsrapporter inom hållbarhetsarbete och adekvat litteratur studerats. För att utvärdera resultatet, har det empiriska materialet analyserats genom kodning. Slutsats: Både ICA Gruppen och MAXI-butikerna har ekonomiska såväl som filantropiska incitament för hållbarhetsarbetet. Det som skiljer dem åt är att butikernas hållbarhetsarbete främst sker i dess närmiljö med konsumenten i åtanke medan ICA Gruppen vill göra en insats för världen. Genom dialog och demokratiska processer sätts gemensamma mål upp. Det finns riktlinjer och olika digitala verktyg samt coacher för att hjälpa butikerna i arbetet. I butikerna sker hållbarhetsinitiativen mer spontant än hos ICA Gruppen. Där är arbetet mer långsiktigt och strategiskt med en tanke på hur varumärket kan stärkas. / Research questions: What motivates ICA Gruppen and the MAXI stores for their sustainability efforts and how do their sustainability goals differ? How do the sustainability efforts of ICA Gruppen integrate throughout the Maxi stores? What strategies characterize the sustainability efforts of ICA Gruppen and the MAXI stores? Purpose: The purpose of this paper is to describe the interaction between ICA Gruppen and the independent MAXI stores of central Sweden, concerning their sustainability efforts. Method: This qualitative study with an abductive approach is based on primary data from five separate interviews with corporate managers of four MAXI stores and one of the CSR managers at the head office of the organisation. In addition to the interviews, scientific articles on relevant theories, research reports on sustainability efforts, and adequate literature have been studied. In order to evaluate the results, the empirical data has been analysed by coding. Conclusion: Both ICA Gruppen and the MAXI stores have financial as well as philanthropic incentives for their sustainability efforts. What differs is that the CSR efforts of the stores take place in the immediate vicinity of the customer, while ICA Gruppen wants to make an effort for the world. Through dialogue and democratic processes, common goals are set. There are guidelines and various digital tools as well as coaches to assist the stores. The stores’ CSR initiatives take place more spontaneously than at ICA Gruppen, where the work is more long-term and strategic, with a view on how the brand can be strengthened.

Vnitřní kontrolní systém / Internal control system

Nováková, Lenka January 2016 (has links)
Dissertation focuse on the internal control system in the enterprises, aims to map the control system by focusing on the purchasing department. I focused on the purchasing process, because with an increasing trends of outsourcing services and the increasing interconnectedness of enterprises increases the risk of fraud currently in the purchasing process. To the research was selected the sample of companies from the banking and non-banking environment, to which were sent a questionnaire focusing on the functionality of the Internal control system in the organization. Banking institutions were chosen mainly because of the strict supervision of the Czech National Bank and the obligations of regular reportin activities are outsourced to supervisory authority, ie the Czech National Bank. Internal control system concept is difficult to define clearly. The main reason is that, in the literature often do not coincide defining the definition of internal control system, and no clear definition of tools, processes and procedures. In Czech Republic is the definition of Internal control system also mentioned in the legislation, and it needs to be understood in very general terms. Schiffer (2009) describes in general terms the Internal control system as a set of operational, financial, personnel, accounting and other controls that are created by management to correct efficient management, compliance with internal rules, asset protection and the most accurate and precise accounting practices in society. Dvoracek (2003) writes that the Internal control system is to be viewed as the sum of interrelated tools, policies, procedures and control mechanisms. In the Czech Republic, for example, contains a definition of the Internal control system Act no. 320/2001 Coll., On financial control in public administration and amending certain laws (Financial Control Act), as amended. Internal control system to be defined as a properly configured system, it must be a grouping of related components and parts, which are gathered into a meaningful whole. Among the elements and parts must be some connection, which is precisely defined.
