Governance forms drivers in bio-pharmaceutial inter-firm relationships
2012
Networking benefits are acknowledged by many studies in the industrial organization and strategic management fields; transaction cost theory agency and property right theory provide the economic foundations to the market-hierarchy dilemma; while Resource based-view (RBV), relational and evolutionary theories provide the strategic foundation of the inter-firm relationships. All this theoretical strands investigate reasons that push firms to formalize their relationship in different governance structures. The bio-pharmaceutical industry has the characteristics to offer to the potential partners both exploitation or exploration alliances benefits. In particular some elements play a “pivot” rol…
The effect of buyer specific-monitoring procedures on buyer control in dynamic supply chain links
2015
Based on transaction cost analysis (TCA), resource dependency theory (RDT), and supply chain management literature, this study explores the effect of buyer-specific monitoring procedures on buyer control in industrial buyer-seller transactions, particularly in relation to how environmental uncertainty affects the buying firm's ability to exercise control over the supplier firm. The research design is based on primary data from a survey of 168 industrial buyer-seller relationships which map a broad set of dimensions of the economic transactions and structures in these business-to-business relationships. The empirical findings provide support for the hypotheses, and demonstrate that the effec…
Drivers influencing the governance of inter-firm relationships in the biopharmaceutical industry: an empirical survey in the Italian context
2013
This paper focuses on factors influencing the choice of the governance form in inter-firm relationships (IFRs) between pharmaceutical and biotechnology companies. By reviewing the relevant literature on transaction cost economics, property right theory, real option and resources-based view, we located some drivers that might influence such relationships and we formulated a set of hypotheses linking them to governance forms. Such a theoretical framework has been empirically tested through a survey conducted among the Italian companies associated to Farmindustria. Empirical results provide some interesting insights on how shaping bio-pharmaceutical deals; we found that the developmental stage…
How the purpose of the inter-firm relationships influences the choice of the governance form: evidence from the machine tool and the pharmaceutical i…
2013
In today's competitive landscape, the choice of the appropriate mode to govern an inter-firm relationship is a critical factor for companies. In the literature several theoretical strands have examined the impact of the purpose of inter-firm relationships on the forms of governance. Building on a robust literature review on the topic, this study focuses on a specific issue influencing the choice of the form of governance in inter-firm relationships, i.e. the purpose of inter-firm relationships with relation to partner's resources. We gather in a unique framework three typologies of partner's resources, i.e. production, R&D and marketing, and through two empirical analyses in two different I…
Pre-requisites of successful strategic electronic coordination : the moderation effect of the ownership mechanism of inter-organisational information…
2017
In this paper, we attempt to explain how the ownership mechanism of an interorganisational information system (IOS) may impact strategic information exchange (electronic coordination) induced by specific investments in the IOS. Recent research and practice show that heavy investments in IOSs demonstrate mixed results with respect to their impact on the electronic coordination. Consequently, the search of additional factors is needed to help and explain under what circumstances the IOS investments for strategic purposes become beneficial for the companies in a buyersupplier dyad. Transaction cost economics (TCE) and the hostage model are used as a framework for the research. 198 observations…
Robustness in railway transportation scheduling
2008
Railway scheduling has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to compute railway scheduling. However, robust solutions are necessary to absorb short disruptions. In this paper, we present the robustness problem from the point of view of railway operators and we give some guidelines to measure robustness in timetabling. We have developed some formulae to compare robustness between two timetables based on the study of railway infrastructure topology and buffer times. Thus, each buffer time is pondered by some factors such as tightest tracks, number of subsequent trains, remaining stations, etc. This method i…
Viability of new road infrastructure with heterogeneous users
2011
This paper explores the importance of heterogeneity in value of time and route choice when assessing the viability of new road infrastructure to alleviate congestion problems. The model incorporates strategic interaction between road operators in a cost-benefit framework and several competitive regimes are considered. It is then employed to establish the financial and socio-economic viability of a congestion pricing demonstration entering Madrid city centre, where road users have to choose between a free but highly congested road and a priced free-flowing road (semi-private regime). A logit estimation is undertaken with information from a questionnaire among road users in the Eastern Madrid…
Optimal Transit Network Design
2019
In this chapter, the optimal transit network design is under investigation. A special kind of transport is assumed to be given the best traffic conditions in a road network (the smallest amount of travel time between origins and destinations). Optimality criteria for transit network design in case of selfish routing are defined in the first section. The Sect. 7.2 is devoted to the estimation of selfish traffic assignment in a network with a transit subnetwork. Optimality criteria for transit network design in case of competitive drivers’ groups routing are defined in the Sect. 7.3. The Sect. 7.4 is devoted to traffic assignment in case of competitive drivers’ groups routing in a network wit…
Efficient GRASP+VND and GRASP+VNS metaheuristics for the traveling repairman problem
2011
Abstract: The traveling repairman problem is a customer-centric routing problem, in which the total waiting time of the customers is minimized, rather than the total travel time of a vehicle. To date, research on this problem has focused on exact algorithms and approximation methods. This paper presents the first metaheuristic approach for the traveling repairman problem.
Improved heuristics for the regenerator location problem
2014
Telecommunication systems use optical signals to transmit information. The strength of a signal in an optical network deteriorates and loses power as it goes farther from the source, mainly due to attenuation. Therefore, to enable the signal to arrive its intended destination with good quality, it is necessary to regenerate the signal periodically using regenerators. These components are relatively expensive and therefore it is desirable to deploy as few of them as possible in the network. In the regenerator location problem (RLP), we are given an undirected graph, positive edge lengths, and a parameter specifying the maximum length that a signal can travel before its quality deteriorates a…
