Strategic capacity planning in the presence of a spot market and a long-term contractual supply channel. / CUHK electronic theses & dissertations collection

January 2007 (has links)
Key words: supply chain management, capacity planning, spot market, long-term contract, contract theory / The long-term supply commitment is made deal through strategic interactions between the players of the supply chain. Game theoretical analysis is conducted to study the bargaining behaviors of the players. Optimal contract design can be obtained in various bargaining power scenarios: Contract Manufacturer Stackelberg, OEM Stackelberg, and Vertical Nash game. We also extend the analysis for single Contract Manufacturer and single contractual customer to multiple customers. The multi-units auction mechanism is also discussed briefly. / This thesis studies the problem of strategic capacity planning for make-to-stock manufacturing systems in the presence of a spot market and a long-term contractual channel in a continuous-time infinite horizon setting. The spot market is run by a B2B online exchange where the sales and prices are random over time while the long-term contractual channel is established by a structured contract in which the price and volume to be delivered are pre-negotiated. / Typically, we consider a supply chain which consists of an upstream manufacturer (e.g. Contract Manufacturer) and a downstream manufacturer (e.g. OEM). The two parties of the supply chain are linked by a long-term contract and both of the parties can trade in the spot market. To study the strategic behaviors of the contract manufacturer and the OEM, we first characterize the optimal operating strategies of the players under a specific contract and then analyze the influence of the contract terms on the optimal policies and the expected profit functions. We find that the optimal contracting strategy of the contract manufacturer can be characterized by a supply curve, which is a price-volume pair and strictly upward slopping, and the optimal contracting strategy of the OEM can be characterized by a demand curve, which is strictly downward slopping. / Pang, Zhan. / "August 2007." / Adviser: Youyi Feng. / Source: Dissertation Abstracts International, Volume: 69-02, Section: B, page: 1305. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 117-122). / Electronic reproduction.

Modeling and solving decentralized supply chain management problems using multi-agent system with dynamic-control agents

Chau, Wan-hin, Derek, 鄒允軒 January 2015 (has links)
Managing large scale supply chains are never an easy task. Numerous researches have put emphasis on supply chain modeling and optimization to assist businesses in searching for the best practices so as to endure the extremely competitive business landscape. To some, the paradigm of centralized supply chain management is adequate for solving its strategic and operational problems. Yet with the improper use of authoritative assumptions, the efficiency of the management process is often jeopardized. Furthermore, current researches in decentralized supply chain are mostly focused on dyadic or linear relationship and seldom consider quantitative modeling and analysis with scalability. Recent development in multi-agent systems provided a means for such a modeling methodology and hence researches in this area. To enhance model representativeness and computational efficiency, vision-based control models that are able to simulate individual operational and strategic traits are developed. In this research, pyramidal agent alignment is proposed for simulating the management-operation dimension with regards to decision exercising and bargaining power management. The system offers one thousand supply chain agents that are simulated in a mono-layer, multi-tier network in real time. Stochastic and dynamic behaviors of the network are handled by statistical regression on scenario-based model evaluation. The proposed design enabled grand scale supply chain modeling and optimization that follows a general or custom simulation supported optimization architecture. Network governance problems and dynamic steering problems are considered and solved using genetic algorithm and dynamic programming. The thesis looks into the potential benefits and limitations of the proposed methods in details, and future research directions are discussed. / published_or_final_version / Industrial and Manufacturing Systems Engineering / Doctoral / Doctor of Philosophy

Supply chain risk management: a logistics perspective.

Bredell, Riaan Daniel 17 June 2008 (has links)
Globalisering het die wêreldekonomie onomkeerbaar verander. Globalisering is onder andere moontlik gemaak deur die snelle tegnologiese vooruitgang en die verstewiging van handelsbande oor landsgrense heen. Dit het tot groter mededinging gelei en organisasies aan nuwe uitdagings en onsekerhede blootgestel. Die unieke aard van die nuwe ekonomie het organisasies verplig om hul tradisionele besigheidsmodelle aan te pas. Dit is nou moontlik om grondstowwe van bykans enige plek ter wêreld te bekom, om produkte naby buitelandse markte te vervaardig of waar die arbeidskoste die laagste is, om produkte vanaf optimale punte te versprei en om produkte bykans enige plek ter wêreld te bemark. Die geleenthede soos hierbo uiteengesit, het die klem opnuut laat verskuif na die belangrikheid van die voorsieningskanaal in organisasies. Die voorsieningskanaal is vandag die kern van die besigheidsmodel van menige organisasie en sluit verskeie eksterne partye van ’n organisasie in, soos byvoorbeeld verskaffers van grondstowwe en vervoerdienste. Dit is vandag van uiterste belang dat die ketting as ’n eenheid optimaal funksioneer, aangesien dit algemene praktyk is dat voorsieningskanale teen mekaar meeding om produkte so vinnig en goedkoop as moontlik aan die verbruiker te lewer. Voorsieningskanale is inderdaad van strategiese belang vir organisasies. Die prestasie van voorsieningskanale het ’n direkte impak op winsgewendheid en is dus ook bepalend in die skepping van aandeelhouerswaarde. Die moderne voorsieningskanaal is egter weens verskeie faktore, soos die betrokkenheid van derde partye, kulturele verskille en die lengte van sekere voorsieningskanale, ‘n onsekere omgewing. Dit is van uiterste belang dat organisasies hierdie onsekerhede of risiko’s na behore bestuur ten einde te verseker dat die prestasie van hul voorsieningskanale aan die verwagtinge voldoen. Hierdie studie het hoofsaaklik ten doel gehad om ’n optimale struktuur vir die bestuur van voorsieningskanaalrisiko’s asook ’n geïntegreerde benadering vir die effektiewe bestuur van die risiko’s daar te stel. Voorts was dit die oogmerk om die benadering in ’n werklike voorsieningskanaalomgewing deur middel van ’n gevallestudie toe te pas. Die voorgestelde benadering tot risikobestuur in die voorsieningskanaal is ’n ten volle geïntegreerde benadering wat alle komponente van die voorsieningskanaal insluit. Dit sluit dus alle eksterne partye van die organisasie in, soos byvoorbeeld verskaffers van logistieke dienste, asook alle relevante ondernemingsfunksies, soos byvoorbeeld aankope, bemarking en finansies. Voorts is dit ‘n gestruktureerde benadering wat op strategiese, taktiese en bedryfsvlakke in die voorsieningskanaal toegepas kan word. Indien dit behoorlik geïmplementeer en toegepas word, kan dit byvoorbeeld onderbrekings in die voorsieningskanaal voorkom of ten minste die potensiële impak van onderbrekings verminder. Dit het heelwat ander voordele, byvoorbeeld verbeterde besluitneming en sakeprestasie. Enige organisasie kan hierdie benadering implementeer. Dit is egter makliker om dit te implementeer in organisasies wat alreeds gevestigde risikobestuurstrukture het. ’n Deeglik beplande implementeringstrategie is ’n voorvereiste vir die suksesvolle implementering van die benadering. Risikopersepsie is ’n wesenlike aspek wat in ag geneem moet word tydens die implementering en die toepassing van die benadering. Persepsies van risiko en risikobestuur word deur verskeie faktore beïnvloed, byvoorbeeld die opleiding en ondervinding van individue asook die organisasiekultuur. Die uitkomste van risikostudies kan byvoorbeeld benadeel word indien risikopersepsies nie na behore bestuur word nie. / Prof. J. Walters
