a r t i c l e i n f o In the last decade, the growing economy in Taiwan has brought about rapid growth in the logistics demands of enterprises. An important goal in the field of third party logistics (3PLs) is to improve the performance of logistics activities to enhance operation efficiency and enterprise competency. However, the employee performance must be determined in order to improve the ...

A field spectroscopy metadata standard is defined as those data elements that explicitly document the spectroscopy dataset and field protocols, sampling strategies, instrument properties and environmental and logistical variables. Standards for field spectroscopy metadata affect the quality, completeness, reliability, and usability of datasets created in situ. Currently there is no standardized...

Cloud logistics comprises the virtualization of logistics resources from different logistics service providers. Those resources are pooled, combined and encapsulated within customer-specific modular logistics services. The pooling within networks comprises a high quantity of available logistics resources and services. Domain-specific structuring with the concept of the logistics service map hel...

There has been considerable interest in the identification of structural properties of combinatorial problems that lead to efficient algorithms for solving them. The notion of backdoors captures hidden structure exploited by state-of-the-art constraint solvers. We prove that strong backdoor identification with respect to the tractable classes Horn and 2CNF becomes harder than NP (unless NP=coNP...

Data streams are an emerging technology for data dissemination in cases where the data throughput or size make it unfeasible to rely on the conventional approach based on storing the data before processing it. Areas where data streams are applied include monitoring of scientific data (astronomy, meteorology), control data (traffic, logistics, networks), and financial data (bank transactions). Q...

The use of RFID (Radio Frequency Identification) tracking in closed systems is replacing barcode as dominant tracking system in many industrial sectors because RFID enables reading multiple objects simultaneously without visual contact. To enlarge tracking systems to cover global supply chains, all aspects related to RFID, such as radio frequencies, data content, transmission protocols, and mes...

In the analysis of MDLAP, this paper creatively combines the mathematical optimization model of cost-based multiple targets distribution location problem into a logistics location selection decision model with a multiple influencing factors, then put forward the method of data standardization processing, entropy weight, the method of principal component analysis and mathematical expressions to ...

the study was undertaken with the objectives to: (1) study the present status of plastic waste management and the existing phnom penh household willingness and their influence factors to segregate plastics for recycling and reuse (plastics & non plastics); (2) study how other cities encouraged and obtained the participation of their population in plastics recycling and reuse and (3) recommend w...

The costing and data mining of logistics costs will become increasingly important to all firms seeking competitive advantages. Activity Based Costing (ABC) is considered as the optimized and most promising method of costing and controlling logistics cost now, and logistics cost data mining based on ABC is playing a very important role in business management. The paper firstly analyses the princ...
