2	Návrh postupu analýzy rizik v projektech technologické přípravy slévárenské výroby / Proposal of a Risk Analysis Procedure in Technological Preparation for Foundry Krčálová, Žaneta January 2018 (has links) The author of this diploma thesis deals with the Proposal of a Risk Analysis Procedure in Technological Preparation for Foundry. Risk management is not currently applied in much detail at this present time. Analysis of the present risk management process in serial and prototype model tools will lead to the identification of risks within this discussion. It is then proposed for corrective actions for improvement of managing the current status to be presented and discussed. Target of this thesis is therefore the proposal of an updated risk analysis procedure in technological preparation for foundry.
3	A New Analytical Model for Tool Life in Metal Stamping Syed, Abdul Vali 05 1900 (has links) <p> Tool life during the precision stamping of stainless steel sheet (AISI 301) has been studied with particular emphasis on reduction in the punch diameter and part hole size due to tool wear. Two analytical models for predicting tool life in terms of number of quality parts that could be stamped between two re-grindings have been proposed using a combination of Archard's wear model and punching force. The proposed tool life models have been verified by experiment trials with a round M2 punch and die. The trials were carried out on a precision progressive die in an industrial environment.</p> <p> The first tool life model calculates the pierced hole diameter variation for a given tool from sheet material properties and gives an estimation of number of parts that could be stamped for a given tolerance on a hole size. The second tool life model calculates number of parts with respect to the allowed burr height. Both of the proposed models are derived using sheet material properties such as sheet thickness, strength coefficient (K), strain hardening index (n) and material elongation (A); process parameters such as die clearance and friction coefficient; punch characteristics such as normalized wear rate, punch diameter and punch edge radius. Finite element analysis was also employed to simulate the hole piercing process to predict burr height. The results from the proposed tool life models, FE modeling and the experiments are in good agreement.</p> / Thesis / Master of Applied Science (MASc)

5	Maîtriser les stratégies de décision : positionnement prescriptif, ébauche et test d'un modèle-outil d'aide à la résolution de problèmes pour les dirigeants des organisations / Mastering Decision Strategies : prescriptive positioning, draft and test of a problem solving model-tool for managers of organizations Vachon, Marc 01 September 2017 (has links) Il existe une inefficience du processus de décision [...] due à un dysfonctionnement de compétence des dirigeants [...]. Pour augmenter l'efficience du processus de décision, les dirigeants doivent maîtriser les Stratégies de Décision, par l'utilisation d'un Modèle-Outil [...] PPPERFFS [qui] répertorie 36 Stratégies de Décision dans les catégories Domaines managériaux, Postures cognitives et Mécanismes cognitifs... / Inefficiency of decision process exists and is characterised by:- simple loop learning,- strictly limited rationality,- and hidden costs of the decision process.The inefficiency of decision process is due to a dysfunction of managers’ competence, who:- lose their decision marks,- lack reflexivity,- use Decision Strategies in beneficial and toxic way, such as:· lack of contradictory mindset (strongly validated hypothesis),· lack of perfectionism (weakly validated hypothesis).To increase the efficiency of decision process, managers should master DecisionStrategies, by using a problem solving support Model-Tool, integrator-facilitator ofDecision Strategies steering, and endowed with PPPERFFS qualities:- "Practical",- "Paradoxical",- "Polyvalent / Exhaustive" (Multi-Skilled / Comprehensive),- "Rapid / Fluent" (Fast / Easy)- "Faithfull" (Reliable),- "Schematic" (Diagrammatic).This Model-Tool has to be drafted and its performance has to be tested.[This has been done:]The drafted PPPERFFS Model-Tool itemises 36 Decision Strategies into the followingcategories: managerial Domains, cognitive Postures and cognitive Mechanisms.
