During the past 15 years Brazil has undergone a process of rapid modernization in its telecommunications. Starting from a chaotic situation, institutional foundations were established and an ambitious development programme carried out. A fundamental piece of this programme was a planning process that proved to be flexible and adequate to handle the social and economic disparities of the country. The policies that have emerged from the planning process were implemented and provided good economic results and satisfaction to customers. 相似文献

Coordination of planning and scheduling decisions in global supply chains with dual supply modes 总被引:1,自引:0,他引:1
Rohit Bhatnagar Peeyush Mehta Chee Chong Teo 《International Journal of Production Economics》2011,131(2):473-482
We address the problem of coordinating aggregate planning decisions and short-term scheduling decisions in supply chains with dual supply modes. We consider long lead time, less expensive sea shipments that are based on demand forecast, and responsive but costly air shipments that are based on revised forecast closer to the demand period. The planning problem determines the sea shipment order quantity and inventory level, while the scheduling model determines the schedule and quantity of air shipments. Results from our numerical experiments suggest that our model leads to consistent cost improvements over a wide range of operating scenarios. 相似文献

Estimating the space requirement for outbound container inventories in port container terminals 总被引:1,自引:0,他引:1
This paper proposes a method for allocating storage space to groups of outbound containers in port container terminals. For this allocation, a collection of adjacent stacks is reserved for each group of containers with the same attributes. The impacts of various space-reservation strategies on the productivity of the loading operation for outbound containers are discussed. A method is suggested for determining the size of the space requirement for outbound container yards. 相似文献

This study delineates the microprocesses of solidarity development and the subsequent collective actions of gig workers in India amidst multiple structural constraints. Using netnography, semi-structured interviews and direct observation, we show how digitally naive app-based cab drivers amalgamate physical and digital spaces, construct a phygital space free of managerial gaze and leverage it to bond and bridge, create webs of care and share and resist multiple oppressive forces, individually and collectively. Thus, we broaden the conceptualisation of worker agency beyond labour-management antagonism and extend the extant literature on solidarity development and resistance in gig work by identifying a spatial enabler, phygital free space and the expansive role of relationship-based commitment. Relationship-based commitment not only functions as a membership mobiliser but also helps mobilise collective resistance when interwoven with an external threat-based identity created through injustice framing. 相似文献

How are breakthrough innovations created? Our study suggests that the type of external knowledge sourced determines the likelihood of creation of breakthrough innovation. We characterize the external knowledge utilized on two dimensions: its technological space and geographic origin. We draw on the concepts of local search and national innovation systems to identify critical knowledge inputs. We hypothesize that external knowledge characterized by technological distance or proximity and the national or international context can have a differential impact on breakthrough innovation. This is due to the contradictory implications of its value created by distance and to absorptive capacity limitations in effectively utilizing knowledge from a different context. To test our hypotheses we use patent data from the U.S. biotechnology industry. Our findings suggest that technologically distant knowledge of national origin has a curvilinear effect and technologically proximate knowledge of international origin has a positive effect on breakthrough innovation. However, simultaneous exploration along technologically and geographic dimensions is not useful to generating breakthrough innovation; technologically distant knowledge of international origin does not have a significant impact.
