Objective: Assessment of the need to study the process of delivering a batch of containers from the rear terminal to the port to ensure uninterrupted communication between the rear terminal and the seaport and delivery a batch of containers exactly on time. As a primary task, the problem of analyzing the factors affecting the nature of the delivery process is solved. Methods: The methods of the theory of probability and mathematical statistics were applied in terms of determining the factors that affect the nature of the delivery process. The method of constructing process models was used to create a technological model for the delivery of containers by a block train to the port. Results: A technological model of container delivery by block train is presented. Diagrams were built showing the share of the main deviations from the schedule of container trains by types of operations for traffic, traction, corporate transport services. The main factors influencing the duration of individual operations with container block trains en route and the increase in the delivery time for a batch of containers from rear terminals to the seaport as a whole are identified. The random nature of the duration of the delivery of containers by block trains following the schedule has been established. Practical importance: The need to improve the methodology for choosing a method for delivering containers from the rear terminal to the port using simulation based on the identified factors influencing individual elements of the technological model of container delivery by a block train, deviations from the delivery time of containers, scheduled running of block trains is shown.

PurposeThe effectiveness of product replenishment and responsiveness of customer service delivery impact largely on satisfaction and retention of customers in retail chain logistics distribution. The fast moving goods in the complex delivery network and limited vehicle resource often lead to long customer waiting time in stock replenishment. With lack of literature systematically reviewing factors affecting retail distribution in inter-store stock transfer services and improving the operations, the purpose of this paper is to analyse and enhance this service for the retail to reduce customer dissatisfaction by developing an integrated quality service improvement methodology and an optimisation tool to improve the product delivery services.Design/methodology/approachThis paper reviews inter-store stock transfer operations and the process capability of an international retail chain, and proposes improvements by integrating Six Sigma, factor analysis, and optimisation modelling. User experience and expectations are evaluated through an empirical survey. A novel principle component factored inter-store stock transfer model is developed to improve replenishment operations. A total of 11 factors affecting inter-store stock transfer delivery time are analysed. An extended model with principal component factors incorporated is developed for the simulation.FindingsTheCpkvalue of 0.51 shows significant difference between the experienced and expected waiting time. With the inter-store stock transfer optimisation model developed, the model assists traffic personnel on the vehicle route planning with multiple pick-up and drop-off locations. The system also ensures the best routing with a minimal travelling time planned, facilitating a reduction of the inter-store stock transfer time, thus improving the customer waiting time. Four significant factors affecting the delivery time are also identified from exploratory and confirmatory factor analysis. The results are analysed with an extended principal component factored inter-store stock transfer model.Practical implicationsThe developed inter-store stock transfer models minimise stock transfer time, increase customer satisfaction, and reduce loss of sales. An integrated service quality improvement methodology has been developed and applied in reviewing significant factors affecting inter-store stock transfer operations.Originality/valueThis paper presents an analysis on inter-store stock transfer operations of an international retail and proposes enhancements on the operations by integrating Six Sigma, factor analysis, and optimisation modelling. A novel principal component factored inter-store stock transfer model is developed to improve the stock replenishment operations.

Reporting Data

The article is devoted to the features of the organization and technology of delivery of perishable goods in small batches by road in regional traffic. It has been established that when planning this type of cargo delivery, it becomes necessary to determine such routes bypassing specified points, at which the time of delivery of perishable goods to points of sale will be minimal. Thus, as a criterion that determines the rationality of building a route network for the delivery of perishable goods in regional traffic, has been defined the time of cargo’s delivery in small batches in regional traffic. The route network for the delivery of perishable goods with a minimum delivery time is considered rational. To analyze the execution time of each delivery phase and take into account the time and quantitative parameters that affect the delivery process, the study built a model which is based on the theory of Petri nets. The parameters of the model were established on the basis of the reporting data of the private enterprise "Samoilenko A.I.". The model took into account time parameters and quantitative factors affecting the process of delivery of perishable goods in regional traffic. An experiment was carried out using the developed model. The obtained value of the integral error of the data discrepancy throughout the system allows us to assume that the constructed model adequately reproduces the process of delivery of perishable goods in small batches by road in regional traffic. Taking into account the results of delivery process’ modeling, using the method of a short connecting network, a rational route network was built in the study, which consists of six routes. The effect was determined as a time difference for the delivery system along the network of rational route network and along the existing network, which amounted to 131 minutes.

The Impact

We studied the impact of predation by cougar ( Puma concolor) on elk ( Cervus elaphus) over a 17 year time span in two watersheds in western Washington. Elk numbers ranged widely in each watershed, from a low of 130 increasing to ≈600 in the Green River and from 600 increasing to ≈1,400 in the White River. We studied adult cow elk survival (n=244) and calf survival (n=548) in both watersheds using radio-marked animals. We manipulated cougar numbers by conducting targeted removals over 7 years and estimated cougar density prior, during, and after the removals. Cougar predation on elk calves was strongly additive (R2=0.80). Cougar predation on cow elk was partially additive in the Green River where other factors had less influence on adult elk survival. Survival of adult cow elk in the White River was less affected by cougar predation than other factors in part due to greater public access. Based on age and femur marrow condition we estimated that 25% of all radio-marked adult elk mortalities due to cougar were compensatory. We have also investigated predation rate by cougar using GPS-marked cougar (n=12). We estimated that 15% of adult elk >= 2 years old that were killed by cougar were likely compensatory and that 75% were likely additive. Removing cougars allowed elk in both watersheds to recover to, or exceed, herd objectives for both watersheds, and restore elk hunting opportunity. Our data strongly indicates that cougar were limiting elk, and that cougar removals allowed elk to escape the predator pit they were in. But simply removing cougar in other elk-cougar systems may not restore elk depending on the relative influence of other factors affecting mortality, amount of additive predation mortality, and suite of interacting predators and prey.

The study investigated undergraduate’s awareness, utilization and satisfaction with online public access catalogue (OPAC) in selected University libraries in Nasarawa State, Nigeria. Four (4) objectives with corresponding research questions guided the study. The study adopted survey research design. The population of the study was 7,233 registered library users (undergraduates) in two (2) public universities in Nasarawa State, namely Federal University Lafia (FULAFIA) and Nasarawa State University, Keffi (NSUK). The sample size for the study was 379 drawn using Taro-Yemene’s formula for sample size determination. Proportionate stratified random sampling technique was used to select the sample of respondents from the two (2) universities under study (i.e.) FULAFIA with 150 and NSUK, 299 respectively. Questionnaire was used as instrument for data collection. A total of 379 questionnaire were distributed and 362 retrieved for analysis representing a percentage of 95.5%. Data was analyzed using frequency counts; mean scores and standard deviation. Findings of the study revealed that, undergraduates were highly aware of Online Public Access Catalogue in selected University Libraries in Nasarawa State. The finding also revealed, undergraduates in selected university libraries in Nasarawa State utilized OPAC to a little extent and students were not satisfied with the use of OPAC, hence their extent of satisfaction derived from the use of OPAC was little extent. Findings further revealed factors affecting use of OPAC by undergraduates in selected university libraries to include: library guide to explain how to use the OPAC is not available, unstable power supply, library staff not friendly, network/server problems, lack of computer systems, among others. Finally, conclusion and recommendations were made based on the findings of the study.

Farm Survey

Using a national farm survey, this study estimates a logit model to identify factors affecting U.S. farmers' participation in agritourism. Of the dummy variables, public access to the farm for recreation has the greatest positive impact, followed by farms near central cities, farms in Rocky Mountain and Southern Plains regions, farmers with college education, farmers paying for farm advice, farms organized as partnerships/corporations, farms enrolled in conservation programs, and farmers with access to the internet. Continuous variables affecting participation include acres of owned land, percent of land unsuitable for crops, operator age, and distance to cities. Targeting farms and farmers with these traits can increase the success of agritourism promotion efforts.

The paper’s purpose is to analyze thirteen variables behind the inappropriate lead time of chicken transportation and determine the factors affecting this distribution. Data, using the snowball sampling method, included 264 questionnaires collected from chicken truck drivers. First, we use the principal component analysis (PCA) to identify the factors contributing to the longest delivery time. We find through PCA that all the variables analyzed take part significantly in the transport time. The most important factors were Connectivity, Resources, Verification & Frisking, Road, and Planning. Improving these factors will optimize the lead time of transport, consequently; improving profitability and animal welfare and quality. The findings are useful to production companies of any fresh products looking to improve their delivery time and increase more benefits.
