Fractional Calculus and Dynamic Approach to Complexity

Beig, Mirza Tanweer Ahmad 12 1900 (has links)
Fractional calculus enables the possibility of using real number powers or complex number powers of the differentiation operator. The fundamental connection between fractional calculus and subordination processes is explored and affords a physical interpretation for a fractional trajectory, that being an average over an ensemble of stochastic trajectories. With an ensemble average perspective, the explanation of the behavior of fractional chaotic systems changes dramatically. Before now what has been interpreted as intrinsic friction is actually a form of non-Markovian dissipation that automatically arises from adopting the fractional calculus, is shown to be a manifestation of decorrelations between trajectories. Nonlinear Langevin equation describes the mean field of a finite size complex network at criticality. Critical phenomena and temporal complexity are two very important issues of modern nonlinear dynamics and the link between them found by the author can significantly improve the understanding behavior of dynamical systems at criticality. The subject of temporal complexity addresses the challenging and especially helpful in addressing fundamental physical science issues beyond the limits of reductionism.

Från sockenkommun till storkommun : En analys av storkommunreformens genomförande 1939-1952 i en nationell och lokal kontext

Wångmar, Erik January 2003 (has links)
The primary aim of this study is to provide a deeper and more complete understanding of why the great municipal amalgamation (storkommunreformen) during the 1940s became the political solution to the problem that the Government believed many of Sweden’s municipalities had in satisfactorily providing for a local welfare society. The study also describes the results of this large-scale reorganization process. The events examined include the political decision-making process at the national level that took place during 1939-1949, as well as the regional/local realization of these decisions during 1946-1952. The parliamentary treatment of the municipal division issue should be viewed as a good example of what researchers have termed a Swedish decision-making model. One clear manifestation of this was the fact that the national commission that investigated the question primarily formulated the principles for the reform. The committee’s proposal received strong endorsements in the reports from the reviewers of the proposal. The government authorities and many of the municipalities felt that a new division of municipalities was justified. Opposition that did occur came mostly from rural municipalities with small populations. Many of these municipalities believed that the present municipal divisions functioned well as they were. Of those municipalities that were affected by amalgamation, 39 percent of them did not agree with the decision. The majority of these could agree to merge with other municipalities, but not with the municipalities stipulated by the authorities. Considering the fact that the then current divisions were based on a long tradition, demands for retaining independence could have been greater. At the same time, it should be borne in mind that 66 percent of all larger municipalities were formed using some level of force. This still indicated a relatively widely distributed opposition to the amalgamation decisions, however.

Research for minor enterprises¡¦s charges on the intuitional decision making. ~By the Kaohsiung metals model industrial¡¦s charges for research object.

Chiu, Ching-hua 18 May 2012 (has links)
Abstract Intuition is one of human¡¦s instincts. It plays a major part in our daily decision-making. However, people experience intuition to different extents. Some may have deeper experience than others. Some may depend much on intuition in making decisions, while others tend to depend more on reason. Although there is risk in intuitional decision-making, many chiefs of businesses believe that intuition can be reliable for decision-making and therefore have made good achievements. The study investigated the intuition-experiential ability and intuition-experiential engagement of the chiefs in Kaohsiung¡¦s metals model industries and the degree of trust for intuitional decision-making of practical management on their company. The study found that the chief¡¦s age and years of service are not related to their trust in intuitional decision-making; intuition-experiential ability is also not related to their trust in intuitional decision-making. However, the intuition-experiential engagement is related to their trust in intuitional decision-making. The academic contribution this study makes is arranging intuitional conceptions and developing intuitional decision-making model, so that people can understand intuition better and come to have faith in intuition. Moreover, it raises Taiwanese people¡¦s interest in the research of intuition. This study concludes that, in aspect of practice of enterprises, chiefs can trust more in and make use of their intuition.

Practical Study on Construction of an Integrated SME Business Decision-Making System-Take P company as an example

Lin, Pei-Huei 27 August 2012 (has links)
This research is based on the case study of P company¡¦s daily operation and business data, to construct its cost evaluation and decision making model. The goal of this research is to fully understand and to model the decision making processes of these small to middle size companies(SME Business) that provide integration services to their customers. The outcomes of this research can be used in prediction as well as optimization of cost evaluation and risk management. The research finds out, through evaluation and modeling, it is possible to reveal the interaction among cost factors, to estimate the lowest cost based on historical data, and to manage risks by coordinating the business partners, in order to make the highest profit from the project. The conclusions of this research are: 1. The high technical and know-how service industrials are relative new and comprehensive in terms of different business domains. Therefore, the risk of cost change is always higher than the other industrials. An accurate decision making model and to estimate project cost precisely is crucial for the business. 2. The case study of P company demonstrates the possibility of using common tools like Microsoft Excel, to manage large multifaceted business data in order to construct an accurate cost decision making model. This may provide a viable and practical solution for small sized businesses that do not have database systems for their decision making application. 3. It is suggested by this research that there are four easy construct, simple use decision making models, which are proven to be useful to lower the risk of budget decision making and to reduce the bias and deviation when these decision is simply based on personal working experience.

Inventory management for the in-flight catering industry : a case of uncertain demand and product substitutability

Swanepoel, Anieke January 2021 (has links)
The in-flight catering industry is a major contributor to food wastage. This wastage is a direct result of the deliberate overproduction of in-flight meals to protect against meal shortages and dissatisfied passengers. With the global strive towards sustainability and the resulting impact of wastage on a company's corporate image, in-flight catering companies need a solution that strives to achieve zero waste and a 100% passenger satisfaction level. This dissertation evaluates the value of combining product substitution and demand uncertainty within an inventory decision-making model as a potential solution opportunity for the wastage dilemma faced by the in-flight catering industry. The decision-making model's purpose is to assist in-flight caterers to make improved decisions regarding the quantity of each meal type to produce for the specific flight under consideration. The model developed is defined as a stochastic multi-objective mixed-integer programming model with fixed recourse and two-way, stock-out based, partial consumer-driven (static) product substitution. The model relies on the output of a forecasting model, that consists of a time-inhomogeneous Markov Chain and a multiple regression model, to forecast the probability distribution of a flight's aggregate meal demand. Due to the lack of available data from public sources, synthetic data is generated to evaluate the model developed. The model is compared against three alternative models that lack either demand uncertainty, product substitution or both to validate the value of including these elements in the decision-making model. The comparison results indicate that the inclusion of the passenger load uncertainty improves the model's average reliability to achieve a 92% minimum passenger satisfaction level with at least 9.2%. Furthermore, it is shown that the stochastic passenger load model produces an average of 2.2 fewer surplus meals per flight instance at the expense of a 3.3% lower reliability when including the substitution behaviour of passengers. This substitution model's superior waste minimisation is attributed to the model's inherent risk-pooling capabilities, and further analysis shows that the value of product substitution increases when the model becomes more constrained. It is, therefore, concluded that the value of product substitution depends on the in-flight caterer's bias towards maximising either reliability or performance. / Dissertation (MEng (Industrial Engineering))--University of Pretoria, 2021. / Council for Scientific and Industrial Research (CSIR) / Industrial and Systems Engineering / MEng / Unrestricted

Dynamisk beslutsmodell för leverantörsval vid komplexa leverantörsvalsprocesser : En fallstudie på Logosol ett litet industriföretag

Hasselblad, Annika January 2017 (has links)
Predictive decision theory explains how humans should make decisions in practice given that they are not always perfect rational decision makers. Based on the prescriptive decision theory, this study addresses criticism of universal decision making models for supplier selections which have the notion of being used uniquely in all types of supplier choice situations. Issues raised are whether this performance is correct and how a dynamic decision-making model could create a more customized decision-making model which does not add much responsibility to the decision maker's judgment. A case study at Logosol, a small industrial company identifies by process mapping a complex supplier selection process consisting of three steps; prototype creation, null-series and production, based on test manufacturing. The supplier selection process is used as the basis for the creation of a dynamic decision making model. Dynamic decision-making models have the basic principle of learning from a decision and using that information in the next decision, which is considered useful in the business case as they not only use test manufacturing for product testing but also for collecting information about the supplier. Finally, the created dynamic decision model shows that universal decision-making models cannot be used in many complex supplier selection processes involving a plurality of steps. The model must be adapted to the company's individual process, however the identification method or some parts of the model used in this study may be used to create a dynamic decision model for other companies or organizations. / Preskriptiv beslutsteori säger hur människan borde fatta beslut i praktiken givet att de inte alltid är perfekt rationella beslutsfattare. Utifrån den preskriptiva beslutsteorin riktas i denna studie kritik mot universella beslutsmodeller för leverantörsval vilka har föreställningen om sig att användas kunna användas universellt i alla olika typer av leverantörsvalssituationer. Frågeställningar som väckts är om denna föreställning stämmer, samt hur en dynamisk beslutsmodell skulle kunna skapa en mer anpassad beslutsmodell vilken inte lägger lite mycket ansvar på beslutsfattarens omdöme. Genom en fallstudie hos Logosol ett litet industriföretag identifieras med hjälp av processkartläggning en komplex leverantörsvalsprocess innefattande tre steg; prototypskapande, nollserieskapande samt produktion utifrån testtillverkning. Fallföretagets leverantörsvalsprocess används som grund för skapande av en dynamisk beslutsmodell. Dynamiska beslutsmodeller har den grundläggande principen att medta lärdom från ett beslut in i nästa, vilket anses användbart för fallföretagets leverantörsvalsprocess då dom inte bara använder testtillverkning för test av produkt utan även för insamling av information om leverantören. Studien visar att föreställningen stämmer, den skapade dynamiska beslutsmodellen visar att universella beslutsmodeller inte är särskilt användbara i många komplexa leverantörsvalsprocesser innefattande ett flertal steg. Modellen måste anpassas för företagets individuella process, dock kan identifieringsmetoden eller vissa delar av modellen som använts i denna studie möjligtvis användas för att skapa en dynamisk beslutsmodell för andra företag eller organisationer.
