Probabilistic alternatives for competitive analysis

In the last 20 years competitive analysis has become the main tool for analyzing the quality of online algorithms. Despite of this, competitive analysis has also been criticized: it sometimes cannot discriminate between algorithms that exhibit significantly different empirical behavior or it even favors an algorithm that is worse from an empirical point of view. Therefore, there have been several approaches to circumvent these drawbacks. In this survey, we discuss probabilistic alternatives for competitive analysis.operations research and management science;

Praktická část obsahuje představení firmy Hana Musilová a jejich konkurentů metodou SWOT analýzy. V poslední kapitole jsou popsány návrhy a doporučení pro posílení konkurenceschopnosti a navýšení počtu odběratelských firem.The topic of my bachelor´s thesis is the analysis of competition. I want to suggest tactics to maintain competitiveness and increase the number of customer companies in this thesis. The bachelor´s thesis includes characteristic and division of competition, describes selected methods of analysis of competition and compares particular advantages and disadvantages of competition. Using SWOT analysis in the practical part of the thesis I will introduce both the Hana Musilová Company and competitors of the Hana Musilová Company. Suggestions and recommendations for strengthening the competitiveness and increasing the number of customer companies are described in the last chapter.Prezenční634 - Katedra ekonomiky a managementu v metalurgiivelmi dobř

General Competitive Analysis with Asymmetric Information

This paper studies competitive equilibria in economies characterized by the presence of asymmetric information (both of the moral hazard and the adverse selection type). We consider economies where non-exclusive contracts (securities) with payoffs dependent on the agents' private information are traded on competitive markets. It is shown that the existence of competitive equilibria is not guaranteed under the dame set of assumptions as with symmetric information.ASYMETRIC INFORMATION ; ECONOMIC EQUILIBRIUM

The Frequent Items Problem in Online Streaming under Various Performance Measures

In this paper, we strengthen the competitive analysis results obtained for a fundamental online streaming problem, the Frequent Items Problem. Additionally, we contribute with a more detailed analysis of this problem, using alternative performance measures, supplementing the insight gained from competitive analysis. The results also contribute to the general study of performance measures for online algorithms. It has long been known that competitive analysis suffers from drawbacks in certain situations, and many alternative measures have been proposed. However, more systematic comparative studies of performance measures have been initiated recently, and we continue this work, using competitive analysis, relative interval analysis, and relative worst order analysis on the Frequent Items Problem.Comment: IMADA-preprint-c

COMPETITIVE ANALYSIS OF U.S. FOOD PROCESSING PLANTS

This paper presents a model-based approach for competitive analysis of manufacturing plants in the U. S. food processing industry. As part of this approach, plant competitiveness is measured using Operational Competitiveness Ratings Analysis (OCRA) -- a new non-parametric method of computing relative inefficiency. Drivers of competitiveness are identified in terms of policies related to plant structure and infrastructure. Policies related to plant structure are those decisions that are related with "bricks and mortar" and have long term implications, such as decisions related to plant size and capacity. Policies related to plant infrastructure are decisions related to how the " bricks and mortar" are used. These policies are typically under the direct control of the operations managers and have a short-term orientation, such as decisions related to equipment, quality, inventory, workforce and confusion-engendering activities (e.g. new product introductions and product variety). The empirical analysis is based on detailed cross-sectional data on 20 processed food manufacturing plants. With respect to plant structure, the results suggest that small sized food processing plants are competitive, and both capacity underutilization and overutilization are detrimental to plant competitiveness. Among the significant results with respect to plant infrastructure, equipment maintenance, quality management programs, packaging supplies inventory, workforce training and product variety are positively associated with plant competitiveness. The results also suggest that introduction of new products disrupts plant operations, at least in the short run, and is negatively associated with plant competitiveness.Agribusiness,

Competitive analysis in banking: appraisal of the methodologies

How do we measure in the banking industry? This article provides an overview of the methodology currently used in competitive analysis and highlights an alternative techniques that could be used to complement this methodology. Given the ongoing process of consolidation in U.S. banking, assessing the competitiveness of financial services markets is an important issue for policymakers.Bank mergers ; Banks and banking
