The research goal of this study was to investigate how supply chain partnerships and customer orientation affect the operational performance of food service companies by moderating flexibility. In total, 725 invitation messages were mailed to members of Ihergo, Groupon, 17P, of which, 166 were returned (a return rate of 22.9 %). Structured equation modeling with PLS analysis allows empirical assessment of the measurement model used in this study. Companies will redefine their business models by connecting suppliers' and customers' view, and by integrating customers' opinions and queries for the planning and development of new products. Linkage efficiency suppliers will reduce inventory and decrease perishable for food service companies based on the driving force to buy in the virtual environment. Product innovation and reduction of the time to market by supplier integration and customer integration are important to food service companies, and flexibility plays an important role in food service companies.

This paper explains and demonstrates the aging performance and structure of bio-asphalt with analytical results from hot stage microscopy, infrared spectroscopic and nuclear magnetic resonance spectra. The experimental results showed that the aging of bio-asphalt is mainly caused by a large amount of coke substance generated during the process, and the addition of BHT can improve the aging resistance of bio-asphalt to some extent. Catalytic hydrogenation facilitate the removal of aldehyde, ketone and carbon-carbon double bond so as to strengthen the aging resistance of bio-asphalt, nuclear magnetic analysis further confirms the results from IR .

It’s easy to cause asphalt aging in the production, storage, transportation and construction sectors; the polar compounds of asphalt in the aging process were studied by using negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry (MS).Test results showed that, with the deepening of aging process, molecular weight of asphalt samples was increasing. Ox class compounds had the biggest content change; Content of Nx class compounds were basically stable; Content changing range of class NxOy compounds was affected by types of compounds. Aging degree of heteroatom compounds was affected by molecular condensation degree, and oxidation rate of low DBE compounds was higher than that of high DBE compounds. The result is of value to analysis of asphalt production and asphalt recycling.
