Abstract This research focuses on the delivery of fresh fruits and veggies via a third-party carrier. Despite the fact that the major concern is transportation, a different fitness function was presented to maximize the transporter's revenues by taking into account specific constraints. The major goal of this study is to figure out how much vegetables and fruit should be bought in order to transport them to various locations at the highest potential profit. Traditional problem-solving techniques are used to address the issue. Furthermore, the simplex approach used allows for the identification of restrictions and the determination of the best solution to the issue that meets transportation needs while also generating the most profit. Overall, the findings show that the greatest profit that can be made in a single trip is $1,840.00, fulfilling three distinct firms' requirements. Research has discussed several ways to solve maximization and transport problems. Nevertheless, this research views them as two separate elements since the transportation method is normally used for minimization. Hence, both this method and the simplex method are coupled to maximize resources.

Abstract While new types of consumer services emerge to fulfill people's diverse requirements, one of the most pressing societal concerns is how to improve the health of the elderly and allow them to live their golden years in good physical and mental health. This research is based on the Whole Systems Research (WSR) method, which expands and improves the theoretical research field of delivery service. The planning and service process of healthy diet opens up new service content and service system for the logistics and delivery industry; the research results of this paper are based on the innovation of systematic service model in three levels: physical, physical, and human, which can broaden the service model for related logistics enterprises and new retail market. The research results of this paper, which are based on the innovation of systematic service model from physical and human levels, can broaden the marketing mode and funding source for related logistics enterprises and new retail market; the overall research process and the application of research method can provide theoretical reference for related research institutions.

Abstract This study aims to review the effects of conventional and organic diet on the diversity of rat intestinal microbiota and look at how intestinal microbiota composition changes the following moxibustion at the Piyu and Zusanli points. A total of twenty-four Sprague Dawley (SD) rats of the Specific-Pathogen-Free (SPF) grade were haphazardly assigned to one of 3 groups: conventional food + moxibustion, conventional food, and organic food. For 12 weeks, organic food was given to the organic category, and typical food was prepared for the conventional category of mices, and mices in the combination category received typical food for eight weeks and administered moxibustion at the Piyu and Zusanli points for another four weeks. Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis (PCR-DGGE) was used to assess alterations in intestinal flora. The content of intestinal microbiota differed significantly across the three groups, according to the similarity clustering analysis. In the combination group, the intestinal bacterial diversity index rose considerably (P < 0.05). Moxibustion at Zusanli and Piyu points enhanced Bacteroides stercoris and Barnesiella intestinihominis growth, according to DNA sequencing. It was concluded that moxibustion has a greater influence on intestinal bacterial diversity than an organic diet.
